I want to highlight a card that caught my attention yesterday and that I employed to a 5-0 run on Arena today.Maybe it's just Orzhov in Ravnica Allegiance being very strong, but this guy does work every single game:

It trades cleanly with two-drops, can chip in for damage in the early game, and is perfect sacrifice fodder for when evasive threats come down and nullify its ability to stall on the ground. Its a low-cost all-around all-star that always picks up value, either by stabilizing early, demanding removal, or trading late.
In this specific deck, it consistently held the ground until my flyers (yeah the 4 Grasping Thrulls are ridiculous) could just take over.
