The other alternative commander Xolatoyac, the Smiling Flood is certainly different

Useless effect

Even sneaking one damage through to your opponent spawns four 3/3s, giving you 20 points on damage on the board after a single attack

To determine the total cost of a spell, start with the mana cost or alternative cost you're paying, add any cost increases, then apply any cost reductions (such as that of Mutated Cultist's second ability)

Its also potentially good later on in some games too, because some creatures have a high power but low toughness or vice versa

Share your thoughts on this years preconstructed decks in the comments, and if you are looking at picking up a commander deck for Christmas (for yourself or someone else) I hope this helped.
