Harvesttide Infiltrator // Harvesttide Assailant

The purest expression of the werewolf flip as combat math: a 3/2 trampler that becomes a bigger trampler when the moon comes out, with the same keyword riding both faces so the size does all the talking. Earlier werewolf designs loaded the flip with new abilities that appeared or vanished on transformation; this one strips that away and lets the transformation register only in the numbers, which makes it a clean piece of connective tissue for any deck actually trying to run the day/night cycle rather than just cash in the marquee payoffs. The two conditions pull in opposite directions and that push-pull is the whole engine: casting no spells on your own turn flips it to night, while double-spelling drags it back to day. Notably, this fits an instant-heavy plan better than it looks, because passing your own turn without a spell is exactly what triggers night, and you can still deploy your interaction on the opponent's turn without pushing the moon back. The trample is what makes the night side worth reaching for: extra power with no way through a chump blocker would sit there doing nothing, but pushing damage past a token is precisely what the larger body buys. Modest on rate, built for a single job: giving a transformation-based deck a body that flips on schedule and hits harder for it.
