Pro Comment: This is another decent peace of fixing and ramp for Green. Paying 3 mana to put this under something bigger, or on top of something smaller, while also searching up a land is a nice deal to me. It helps you splash while also giving you some Mutate synergy.

Pro Comment: You need to do way too much to make this work. It just won’t happen.

Pro Comment: So I would feel fine about playing a two mana 2/2 with Flash anyway -- can occasionally ambush a more expensive creature with 2 toughness, or a creature with less than two power, and it has fine stats. But, reducing the cost of spells with Flash is nice too, especially because there seems to be a decent amount of it in this set.

Pro Comment: So, one thing that is kind of sad when you cycle away a big creature you can’t play early, is that sometimes you get to the late game and that creature sure would be nice to have in your deck! Well, Yidaro fixes that for you. You can cycle it away early to hit a land drop or whatever, and then you have a chance to draw him again later. Sometimes you’ll just be want to cast him at that point since he haste, Trample, and a massive body -- but other times you still won’t have the mana, but you can cycle him again! Cycling him the 4 times probably won’t come up again in Limited, but hey, it isn’t impossible.

Pro Comment: This is another very good Cycling payoff who can make life a nightmare for your opponent. Every single time you attack with this your opponent has to make a choice between potentially taking a ton of damage to the face, or throwing a creature in front of it that will probably just die, since First Strike and even just one +2/+0 is enough to make the Marmoset win combat most of the time.

Pro Comment: Three mana for a 4/5 with Menace is crazy good, and while giving your opponent a deathtouch counter isn’t awesome, there are lots of situations where that just doesn’t matter! Like if you play this one turn 3 and your opponent has nothing. Or, you play this on turn three, and then kill whatever you put the counter on next turn. Even when those optimal situations don’t emerge, the fact this is so big means that your opponent will frequently have to double-block anyway. And hey, even if you just end up trading 1-for-1 with this thing, that’s not too bad of a deal.

Pro Comment: Even on its own, it is pretty likely that the Crusher will make a dinosaur when it attacks. As a 5-mana 6/6 with Trample, it has the kind of size that is a real problem. And, if you happen to have something with trample in play the turn you play it, it can actually impact the board right away when that creature attacks! This thing will just snowball as more dinosaurs with Trample get made, and it will take over the game.

Pro Comment: As always, this provides excellent fixing. It lets you splash a card off of only a single basic land, and that’s great consistency. Even in a two color deck, the impact it has on your mana is substantial.

Pro Rating: 3.0
Pro Comment: This is certainly situational, but also fairly efficient. You’re going to be spending only two mana to kill something, which will usually be less than your opponent paid for their creature. It might fall a little short of premium, but it is a nice removal spell.

Pro Comment: A 3-mana 2/2 that draws you a card when it hits the opponent would probably normally be kind of alright. It has a great ability, but actually getting in to draw you that card is difficult pretty much all game. But, this isn’t an ordinary format. There are keyword counters all over the place, and of course there is mutate. Playing this on turn 3, and then mutating something on to it later that has more size and/or abilities is going to feel pretty good. You still are dealing with a kind of ugly fail case on this little guy, but I think the upside is real enough that you end up playing this in most of your Blue decks, and it may even be better than that if you have enough Mutate going on. One combo with a couple of Commons is to play Otter turn 3, and then mutate the Heron onto it on turn 4 -- suddenly you have a ¾ flyer that draws you a card when it mutates and when it hits the opponent. This will happen a lot in this format.

Pro Comment: A two mana ⅓ that reduces the cost of cards with Mutate would probably be a nice payoff to have in Mutate-heavy decks. It gets even better since the Symbiote lets you loot whenever it mutates, which is pretty great.

Pro Comment: A 3 mana 3/3 that gains a random keyword ability or +1/+1 counter each combat is pretty nice. I also like that it makes sure it doesn’t ever give you double of the key word counters, which would obviously be useless. So, if left out long enough the Giant becomes a 4/4 with all those keyword abilities -- that isn’t ultra likely or anything, but just getting more and more powerful every turn seems is great! And it is colorless, so you know you’ll get to play this 100% of the time.

Pro Rating: 3.0
Pro Comment: I am usually interested in running one Divination in most Limited formats, and this is a strictly better one since its cost can be reduced. If you are consistently casting this for one, it will be absolutely silly -- but the requirement it asks for, while doable, isn’t the kind of thing that will just always be the case.

Pro Comment: 3 mana for 4 damage at Instant speed is already premium and the additional value this gives you is nice, as you can use it to do some damage to your opponent too. And sometimes, killing their X/1 and doing 3 to them will just be game over. Don’t get me wrong, most of the time you should kill something bigger, but if the spillover damage here is going to be lethal for your opponent well -- obviously, you should do that.

Pro Comment: Two mana for three damage to a creature at instant speed is already premium, because it tends to be efficient enough to trade up pretty often. But, adding this card selection ability is a nice upgrade It will play much like rummaging would, except that you don’t get the card in the graveyard, so sometimes it will be weaker that rummage, but most of the time you wouldn’t know the difference. This is definitely premium removal -- kills something and then helps you find more gas, and I always like that.

Pro Comment: Another highly situational card with one mana cycling, Startling Development is much better than it looks. The 4/4 part will come up sometimes, and when it does it will be nice! But yeah, the real power here comes from being able to Cycle away for one mana.

Pro Comment: As always, these provide nice fixing, and the 1 life is a solid bonus.

Pro Comment: This is situational for sure, but this format has a whole lot of big bois, so it is a little better than usual. It is also an Instant, which means you can sometimes really get a blow out.

Pro Comment: Neither option here is great, but neither is bad, either.
