Supportive Parents

Convoke run in reverse: rather than tapping bodies to help pay for a spell, this 3/3 converts any two untapped creatures into a single mana of any color, at instant speed, whenever you want it. The exchange rate is intentionally punishing. Two creatures for one mana is dreadful in isolation, which is precisely the point: the ability only becomes worthwhile once the board is wide enough that the tapped creatures were going to be idle anyway. That constraint dictates its home: a go-wide green shell with a token engine, where a swarm of expendable bodies already sits on the table and the marginal cost of tapping a pair of them rounds down to nothing. In those builds it doubles as color fixing and acceleration a creature-flooded board can fund without leaning on lands, handy for off-color splashes or emptying a glut of one-drops into something expensive. The for a 3/3 is a respectable enough attacker that the ability lands as bonus rather than the sole justification for including it. The friction lies in the creatures staying tapped: every activation is a genuine tempo cost, forcing a choice between mana now and an attack or block later, never free ramp. It is a support piece in the literal sense, a payoff that only pays once a token strategy has already put the work in.
