Party Thrasher

Two abilities that most designs would keep in separate slots, welded together so each one feeds the other. The first-main-phase filter is a spin on impulsive draw: discard a card, exile the top two, keep access to one of them for the turn. That "this turn" clause is the usual pressure valve, the reason impulsive draw stays fair, since the card evaporates if you cannot deploy it. Then the top line quietly dissolves that pressure. Anything noncreature you cast from exile gets convoke, so the 1/4 body and its friends can tap to pay for the spell you were about to lose. The rummage that fuels graveyard decks now doubles as a mana engine that only exists off exiled cards, and the two clauses are pointed at exactly the same zone. The reward is for casting spells you no longer hold, and it prices its own advantage in board presence: the more creatures you have to tap, the deeper into your exiled pile you can reach. The stout toughness is not incidental either, letting the Lizard Wizard survive combat and remain available to convoke on the following turn rather than trading itself away. What looks like a value creature stapled to a mana rock is really one continuous loop, with the discard feeding the exile and the exile feeding the mana.
