I do feel you on the engine-building cards feeling so drawn out in this day and age of MTG, but I do like Barrin's focus on a trigger that feels a bit underrepresented in the card space. And I do really love the new ways in which WotC is trying to get away from redundant "draw a card", "create a 1/1 token", "gain a life, lose a life" effects in new card designs. Notably, evergreen tokens like Clues, Treasure, and Blood go a long way to feed into other engine pieces that care about artifacts entering/leaving the battlefield or discarding cards to Blood. Effects of one engine piece bleeding into multiple other potential engine triggers makes assembling these components in a draft and in game a fun little puzzle.Barrin has always felt gross to me. Frankly, the whole "do a thing, draw a card" paradigm of engine-building feels incredibly uninspired and on-rails. It's probably just a me thing, though.
