Were also adding Phylath, World SculptorPhylath, World Sculptor, which many would refer to as Avenger of ZendikarAvenger of Zendikar we have at home. While I agree its a lesser version of Avenger, its ability to turn Yumas Plant Warrior tokens into 8/6s, or higher, gives it a huge boost here
But where this deck really shines is in its ability to not only bring out plenty of creatures and creature tokens to fuel your convoke (through cards like Goblin Instigator and Battle Screech, which both produce creature tokens, but also reward you for creatures you'll be tapping outside of combat to fuel said convoke
Magic has a reputation for complexity and expense that isnt entirely unearned
You'll need to be careful when deck building that you don't cram too many of those uninkables into your deck and end up with a hand full of them
Its also become much easier of late for Burn decks to play more White sources, so they can bring in Path to Exile as an additional effective answer to the Firewalker
