Horde of Notions

The five-color Elemental king gates its tribe's recursion behind its own identity: the activation costs the full WUBRG again, so even after the body is on the battlefield, every return spell demands all five colors before the engine produces anything. That tax is what turns an ability reading as generous into one that plays as a grind. What it buys is a tribal payoff that sidesteps the usual reanimation tension. Instead of one-shot recursion, the king lets the same Elemental come back turn after turn, since the card it plays simply re-enters the graveyard once it dies again. Pair it with a death-trigger Elemental and the rainbow tax pays for itself indefinitely. Vigilance lets it hold the fort without surrendering an attack, haste means it threatens the moment it lands, and trample keeps chump blockers from buying time while the loop assembles. Elemental as a creature type has always been the most color-spread of the major tribes, scattered across every shard and wedge, which is what makes a five-color leader feel native rather than bolted on. This is the design that says the quiet part out loud, demanding every color precisely because the tribe lives in all of them. It asks nothing subtler than a graveyard stocked with Elementals that want to die and a manabase that keeps the rainbow flowing.
