This is a budget deck upgrade for Savage Lands, the Gruul (R/G) Starter deck on MTG Arena unlocked through the Color Challenge.

This Deck Upgrade costs: 3 Common WC's || 8 Uncommon WC's || 0 Rare & Mythic WC's
All other cards in the deck, including the rares and mythics, are obtained for free from the other Arena Starter Decks.

Although the preconstructed deck is mostly built around the Landfall theme, we've leaned away from that strategy in favor of a more generic aggressive deck since Landfall is not very budget friendly or competitive. Gruul has access to some powerful and aggressive creatures, even on a budget, so let's look at some of our upgrades.

CREATURES

Battle Cry Goblin is a really solid two-drop for aggressive red decks, even without a goblin theme. The thing we like most about this card is that it's a solid play on turn 2 and it's a solid play if we top deck it later in the field thanks to its mana sink ability. Emergent Sequence is a sorcery, but I'm going to include it as a creature since that is the role it fills in our deck. It plays well with our 4 copies of Brushfire Elemental, gets another snow permanent out on the field for our Spirit Bear, and gives us some ramp options while still being a decent body early. Hulking Bugbear is our main turn 3 play. I messed around with Boreal Outrider in this slot but it was just too slow and I came to appreciate the bugbear as a simple 3/3 haster. It's also a goblin so we have some minor synergy with the Battlecry Gob. Spirit of the Aldergard is our turn 4 big beater and he can get big very quickly if our opponent doesn't deal with it. He also fetches a snow land from our library to keep the landfall triggers on our Elemental rolling and get us to our 5-6 mana drops for closing out the game. 

REMOVAL

If we're going to be aggro, we need our removal to be cheap and efficient. Lucky for us Blizzard Brawl and Frost Bite are just that. I'm only running 3 copies of each because it's been a decent amount for handling the aggro matchups like mono white without significantly hampering our chances against the popular control and ramp decks. 

POTENTIAL UPGRADES

While Gruul is not one of the top decks in the 2022 Standard, there are still some upgrades we can make. The best place to start is usually with lands.

CREATURES

 Jaspera Sentinel is not included in this upgrade list because it mainly synergizes well with Magda, Brazen Outlaw. So I would only include 4 Sentinels after also upgrading the deck to include 4 Magdas.
