Mirage Phalanx

Soulbond usually offers a shared keyword or a static buff, a one-time handshake between two bodies that costs nothing to maintain past the pairing. This one weaponizes the pairing itself into a doubling engine: once linked, both creatures spit out a hasty copy at the start of combat, so a modest partner suddenly gets its stats and abilities stapled onto a temporary token every turn. The tokens exile at end of combat, which is the constraint doing the real work: nothing sticks, the board never snowballs past a single swing, and the whole apparatus collapses the moment either creature leaves. That makes the pairing a genuine decision rather than a formality. The math favors attack triggers over enters-the-battlefield ones: because the original creatures are already in play, only the two fresh tokens enter each turn, but every copy plus every original swings, so a creature that does something when it attacks fires that trigger twice per pairing while an enter-the-battlefield payoff only banks the token's single arrival. Leave it paired with vanilla stats and you get a bigger alpha strike and little else. It rewards asking not "what has a good keyword" but "what wants to attack repeatedly and drag a haste-enabled clone along for the swing." The 4/4 body for six is deliberately unremarkable, because the card is not selling its own statline; it is selling the multiplier it grants, and the exile clause keeps that multiplier from compounding into an unbeatable position.
