Thunder-Thrash Elder

Devour 3 is the steepest exchange rate the keyword ever offered: every creature you feed in returns three +1/+1 counters, so the printed 1/1 is just the seed of a threat scaled entirely to how much board you're willing to liquidate. The card functions as a converter, turning a stalled-out battlefield of expendable tokens and chump bodies into a single oversized body, trading width for height as it enters. That conversion is also its whole vulnerability. Everything stacks onto one creature with no protection attached, which means a single removal spell undoes an entire turn's worth of fodder, and the sacrifices lock in the moment it enters: there is no choosing partway through, no holding back if the math turns sour. The keyword rewards decks that already want bodies on the table for other reasons, the kind of aristocrats shell where the creatures being eaten were never expected to survive anyway, and it punishes any plan that asks you to play fair off the top of your deck. Among the early devour designs, the multiplier of three sits at the aggressive end of the dial: the version that promises the biggest payoff and demands the most commitment to claim it.
