Planewide Celebration
"Choose four, and repeat allowed" is the whole engine: a menu of only four modes yields thirty-five distinct combinations, and any single mode can be spiked to maximum by picking it all four times. That repetition-friendly structure is the justification for the seven-mana cost, because none of the four options is individually worth close to that rate. Two Citizen tokens and two proliferates, or four permanent cards back from the graveyard, or a flat sixteen life, or any blend: the card bends to whatever the board and the graveyard offer. Proliferate on the menu is the load-bearing choice, and the reason to slam this into a deck built on counters rather than a fair midrange shell; stacking it three or four times turns a modest +1/+1 or loyalty investment into a decisive one, while the token and lifegain modes keep the spell live even when the board holds nothing worth advancing. The design trades raw efficiency for a guarantee that seven mana is never dead: some legal set of four modes always does something. That is the bargain underneath every big modal spell, and this one leans harder into repetition than most, which is exactly why it reads as a top-end payoff rather than a role-player.
