At the beginning of your upkeep, if you have 40 or more life, you win the game.

Descendants' Path

At the beginning of your upkeep, reveal the top card of your library. If it's a creature card that shares a creature type with a creature you control, you may cast it without paying its mana cost. If you don't cast it, put it on the bottom of your library.

Lord Windgrace

[+2]: Discard a card, then draw a card. If a land card is discarded this way, draw an additional card.
[−3]: Return up to two target land cards from your graveyard to the battlefield.
[−11]: Destroy up to six target nonland permanents, then create six 2/2 green Cat Warrior creature tokens with forestwalk.
Lord Windgrace can be your commander.

Yarn unspooled, squeaky toys de-squeaked, upholstery torn to shreds—it was carnage.

Violent Outburst

Cascade (When you cast this spell, exile cards from the top of your library until you exile a nonland card that costs less. You may cast it without paying its mana cost. Put the exiled cards on the bottom in a random order.)
Creatures you control get +1/+0 until end of turn.
