Modern Horizons 3 Tier List: The criteria The criteria for my tier lists is fairly strict
The commander not only sets the tone for the deck but also determines what cards can be included based on their color identity
With Urza at the helm of your deck, you can take advantage of his ability to create a 0/0 Construct creature token when he's cast, as well as tap artifacts for mana
Now comes the difficult part: between Carmen and Clavileno I actually think Carmen has a much higher power ceiling, but to reach that ceiling you'd need to start moving away from Vampires and into more efficient sacrifice triggers (Pitiless Plunderer) and lifegain payoffs (Archangel of Thune)
My Favorite: Depthshaker Titan I think its a bit risky to turn all of your artifacts into 3/3s but its definitely a way to surprise everyone and close out the game when they all get melee, trample, and haste
Besides, owls are cool and it has like 15 different printings
