Goal:
1) Deploy Steel Leaf Champion and Gigantosaurus early with help from Llanowar elves and/or servant of the conduit
2) Draw a bunch of cards with Rishkar's Expertise (5 or 10).
3) Cast a (free) Baral's Expertise for free and bounce the three permanents you're opponent's played and drop another steel leaf champion
4) Meanwhile, you've been attacking for 5 or 10 or 20
Exclusion Mage is awesome.
If all else fails, just Memory and do it again
I was tempted to go blossoming defense and heroic intervention in the board but ultimately decided the deck spell pierce and negate were better options, after a couple games I shaved a few copies of each, ultimately:
Crushing Canopy - Flyers, enchantments
Deathgorge Scavenger - Graveyard hate
Jace's Defeat - Counter counter
Negate - Non creature one for one
Nezahal - Long games, good for going over the top
Nissa - Card advantage, recursion
Search for Azcanta - Card advantage
Spell Pierce - Suprise stop to settle, fumigate, contempt, etc
Thrashing Brontadon - Artifact and enchantment hate
Torrential Gearhulk - Flashback a canopy or another spell
Deck feels pretty good, can't wait to get feedback and suggestions
