Pro Comment: This is hard to chump block, and it can end the game in two swings thanks to Toxic. The stat-line isn’t amazing for the cost though, and there will still be enough boards where your opponent can just double block it to take it down. It also doesn’t deliver any bonus value you get to hold on to in the event it gets destroyed, and if I’m going to spend 7 mana, I feel like I should get something, even a bit of life or a 1/1 token would make a big difference.

Pro Comment: One mana tricks have been some pretty serious business of late, and I think this looks like another solid one. This kind of gives you two separate uses, which is great for such a low cost! First it can be used as a traditional trick to help your creature win combat with the +1/+3 boost – but you can also use it before your opponent blocks to make a big creature take to the air and crack in for a bunch of damage – along with some toxic upside

Pro Comment: This seems like it takes too much work. If you play it early it will definitely build up counters and then reanimate something at some point, but if you get it in the mid to late game, it is likely to be a little too slow to actually do anything, and that’s a huge downside

Pro Rating: 3.5
Pro Comment: This is a very nice common. A three mana 3/2 with Toxic 1 is already probably playable, so the fact it spits out a Mite when it dies is sweet. It is worth noting that the token’s inability to block does lower the value of the token – more than adding Toxic 1 makes up for

Pro Comment: This always provides some solid fixing, even for two color decks. It can be particularly appealing when you are splashing one card, as just a single basic land and the Expanse are often enough to make that work.

Pro Comment: This isn’t the most impressive planeswalker for Limited. Sure, he has a +2 that technically draws you a card and a -3 that is technically removal, and those things are usually pretty good – but both are fairly weak versions of that effect. The +2 can only net you a Mountain, and the -3 is dependent on the number of Mountains you can control. Even the ultimate demands you have mountains – though obviously if you can fire off the ultimate and then use the +2 every turn to grab a Mountain you’re going to wind, but that’s going to be tough, since Koth doesn’t do much to protect himself. So, to some extent, Koth is an incentive to go Mono-Red or close to it, and if you can do that, obviously the -3 will kill most stuff, but on a board that is built out at all, your opponent can still easily deal with Koth

Pro Comment: Overall, she doesn’t seem like a super impressive planeswalker for Limited. Effects like her +1 are usually pretty underpowered – you can certainly force an attack that is bad for your opponent, but it is still super situational – you won’t always accomplish something by using it. Her other +1 lets you rummage, which is solid but unexciting – but it does set up her 0 loyalty ability – which can be pretty good if you have a well-stocked graveyard. Still, the token she can make is restricted in several ways – it has to have a low enough mana value, and it only gets to swing once. She can work pretty well with the “For Mirrodin!” Equipment in the set, because the tokens those Equipment make will stick around. But still, she doesn’t come with a real removal effect, she doesn’t protect herself, and she doesn’t even net you cards. Usually a great Limited Planeswalker does 2 or more of those things, and we’re being generous here if we say she is doing 1 of 3 of them! All of that said, she isn’t a bad card, just sort of a situational value-engine type planeswalker, and not one that takes over games. If you’ve managed to stabilize or you’re ahead, her 0 ability will definitely pressure your opponent – but if you’re behind, this is a pretty ineffective planeswalker

Pro Comment: This is great removal. -4/-4 is enough to kill the majority of creatures, and this is cheap enough that you can trade up in a big way. If you get value out of Proliferate too it will feel truly absurd

Pro Rating: 2.0
Pro Comment: One mana for +2/+2 tends to be a pretty solid boost, as you can very cheaply allow your creature to win a lot of combats. The oil counters really matter for some cards too, though sometimes you’ll end up adding oil counters on something that can’t really do anything with them.

Pro Comment: This can threaten to become a 4/4 any time it swings, which is pretty nice. This kind of card often gets through without you actually having to sacrifice anything to it, because the opponent just can’t muster a good block. This also combines well with the various sacrifice synergies, and being a free Sacrifice effect means it has the upside of working really well with Red’s usual Threaten effect.

Pro Comment: Obviously, this has some very impressive efficiency. It can also come down and do something right away thanks to Haste! Ward also means this can’t be dealt with efficiently. Toxic and Trample might seem like a strange pair, but its actually pretty great! If your opponent takes any damage at all from the Rex, even 1 trample damage, they end up with 4 poison – and you still destroy their creature. Triple Green can be surprisingly hard to get in Limited, but I still think this does enough right away, and is hard enough to deal with, that it is a bomb.

Pro Comment: The cards in this mega-mega cycle have pretty much always been bombs. Even just +2/+2 and protection from two colors is a huge problem in a lot of games – with everyone playing two color decks, there’s a pretty good chance Red or Green is one of their colors! Obviously though, its the effect you get when you hit your opponent that makes this really good, as it will just start drawing you extra cards at a pretty crazy rate! You can get up to two extra cards when you hit your opponent, and it even makes sure you get some value if you hit two lands. So yeah, it grants an efficient boost, one that can be moved around all game long, and grants serious card advantage. I think it does enough to be a bomb, like most of its predcessors.

Pro Comment: A one mana ½ with Toxic 1 will get some poison going if you play it on turn one, and it does have an ability that keeps it somewhat relevant. It gives your opponent a poison counter if you target your own creature with a combat trick (and there are several solid ones in Green) and if they remove one of your creatures too, which means this card will pretty consistently chip in at least one poison.

Pro Rating: 4.5
Pro Comment: This is expensive, but it does give you quite the impressive creature. Ward 3 and pay three life is pretty legit, as it makes it harder for your opponent to efficiently deal with the Goliath, and they are going to take a hit in terms of their life no matter what they do – and that’s the fail case here. Then, if you untap with it and cast some noncreature spell, the game is pretty much over, since you make an army of tokens that can either allow you to finish your opponent off or gain a massive advantage on the board. You won’t always find yourself able to do that of course, but you’re still talking about a 6/6 Flyer that is an absolute pain to kill. I think this sneaks into the lower “bomb” range, since it gives you solid value even if the worst-case thing happens, and if it sticks around, you’re just going to win.

Pro Rating: 2.5
Pro Comment: These all offer great fixing, like most dual lands, and the fact that they enter untapped early is pretty nice.

Pro Rating: 0.0
Pro Comment: This has a cool design! Especially because it even gains the ability to tap for mana, but this won’t amount to much more than a hard-to-use 3 mana mana rock, and that’s not worth a card in Limited.

Pro Rating: 4.0
Pro Comment: This is a sweet reprint, and a great card! It doesn’t add to the board, which seems like it has been a liability in lots of sets lately, but the card advantage it grants you can really allow you to overwhelm your opponent. Losing life is a fine price to pay for something this powerful. I think in the old days of Limited it was definitely a bomb, but in this world where getting on board early has become increasingly important, it probably tops out at 4.0

Pro Rating: 2.5
Pro Comment: This has a solid stat-line and an ability that will be useful on occasion. You can definitely find situations where sacrificing something with this can net you some nice mana to cast an artifact, but more often than not, the ability won’t matter

Pro Comment: A 5-mana 5/5 Vigilance Vehicle with Crew 3 is probably a 1.5. That’s just not a very good rate for a card that isn’t a creature unless you do some extra work! The fact this comes with an oil counter does matter though, as it does make it so this can be a creature all on its one for one turn, and if you proliferate it can become a real problem. Of course, the upside there is still that this is just a 5-mana 5/5 with Vigilance – which is nice, but again – there is work to be done to even get it to the point where it does that consistently.
