Molten Echoes

Red rarely gets to be the color of compounding creature value, and this is one of the few tools that lets it: a tribal copy engine that fires whenever a nontoken creature of the chosen type enters under your control, however it got there. That "however it got there" is the part that matters most. It reads as a cast payoff, but the trigger keys on entry, so it happily pays out on reanimation, blink, and anything that cheats a body onto the battlefield, not just hardcast creatures. The haste-and-exile clause is what pays for an open-ended effect at this cost: you get an immediate attacker or blocker plus a full slate of enter-the-battlefield triggers, but the copy vanishes at the next end step, so the reward is a burst of tempo and triggers rather than a permanent board. That timing steers the card toward creatures whose value is front-loaded: mana dorks that ramp the instant they arrive, and bodies whose entry triggers fire regardless of how long the copy lingers. Restricting the trigger to nontoken creatures is what keeps it from stacking with itself or with other token-doublers into an unbounded loop. And because the type locks in as the enchantment resolves, it rewards committing to a single tribe hard enough that most of your creatures qualify, favoring entry effects over bodies whose worth lives in repeated combat. Built toward, not dropped as a finisher.
