Darigaaz Reincarnated

Killing this Dragon starts a three-turn countdown, not a burial. The death-replacement is the whole engine: rather than dying, it exiles itself with three egg counters, then sheds one each upkeep until the clock runs out and the 7/7 reassembles on the battlefield, flying and hasty and swinging again. The mechanic literalizes the Dragon-egg flavor of Darigaaz's lineage and turns it into a recursion that punishes the obvious answers. Spot removal, combat, board wipes: all of them merely send it home to incubate, and once it sits in exile with egg counters, it is beyond the reach of ordinary removal. Destruction and bounce target permanents on the battlefield; the incubating card is untouchable by both, which is precisely why the resurrection is so hard to interrupt. The answers that actually work sit at the edges of the cycle: hand disruption or a counterspell before it ever lands, or exile-based removal that never gives it a chance to die. Exiling the Dragon straight from the battlefield sends the card to the exile zone with no egg counters, bypassing the death replacement entirely, so it never begins the incubation clock and never returns. Everything else is a reprieve, not a solution. The cost of that resilience is patience and a wide seven-mana bill across three colors: when it does die, its controller surrenders the body for the better part of three turns, a real tempo concession against a deck that can exploit an empty board. It trades immediacy for inevitability.
