Mythos of Illuna

Cast on blue alone and it is a plain clone: copy any permanent the board hands you, a threat, a mana rock, a planeswalker, no strings attached. Route the two generic pips through a red source and a green one instead, and the token arrives with an enters-the-battlefield fight trigger stapled on. That fight only pays off if the copy is a creature, so a duplicated rock or walker off the same enemy mana still just yields the copy with nothing to swing. This cycle gave each color a signature spell and a splash upgrade unlocked by paying a specific enemy pair; the copy version is the one where the upgrade rewrites the card's posture rather than merely sweetening it, turning a flexible clone into a clone that can also kill the creature it was copied from. What settles which mode you get is the mana you spend up front, not a target declared in advance. The second decision comes a beat later: once the enhanced token enters, its fight trigger goes on the stack, and you pick up to one creature you do not control as the trigger is put there, right after the spell finishes resolving. The floor is a serviceable blue clone; the ceiling is an enemy creature reproduced as your own and swung into its original in the same breath, removal and threat welded together. The toll for that ceiling is spending half the cost outside blue, and the design asks nothing extra of you when you cannot pay it.
