Circular Logic

Whenever a player cycles a card, you may exile target creature. If you do, return that card to the battlefield under its owner's control at the beginning of the next end step.

All lands you control become 1/1 creatures until end of turn. They're still lands.

Target player reveals their hand, then you choose a card other than a basic land card from it. Search that player's graveyard, hand, and library for all cards with the same name as the chosen card and exile them. Then that player shuffles.

Destroy target creature. It can't be regenerated.

Enchant creature Enchanted creature gets +2/+2 and has trample. Whenever enchanted creature deals damage, you gain that much life.

Trample Madness 2G (If you discard this card, discard it into exile. When you do, cast it for its madness cost or put it into your graveyard.)

Target player sacrifices a creature of their choice. Flashback 5BB (You may cast this card from your graveyard for its flashback cost. Then exile it.)

T: Add B. This creature deals 1 damage to you.
