Devotion, as a mechanic, mostly reads static: count your green pips, cash them for a fixed bonus or a body scaled to the total. This one takes that same counter and pours it into a combat modifier instead, turning your board's accumulated green into a one-turn power spike on a single attacker. The 4/3 body arrives already contributing to the count, so the trigger it brings almost always resolves for more than zero, and in a build stacked with green permanents it can hand a creature a lethal-sized number the turn it lands. That framing puts it in a different lineage than the devotion payoffs that ask you to hold the count over multiple turns: this is a burst, spent immediately, best when your board is widest and your green symbols are already on the table. The +X/+0 is deliberately narrow (power only, one target, one turn), which keeps it a finisher rather than a wall-builder; it wants to close, not stabilize. It rewards a deck that has already committed its green to the battlefield and needs one push to convert that commitment into damage, which is a cleaner and more aggressive use of devotion than most of the mechanic's payoffs bother to offer.
