A quick recommendation from my and other players experiences with the deck is to swap the face commander, Szarekh, the Silent King, for the alternative commander Imotekh the Stormlord
Then, it allows sources controlled by the owner that deal damage to an opponent or permanent to deal that much damage plus the number of fire counters of Fated Firepower, meaning that 3 counters would make a 1/1 creature deal 4 damage, instead
Today, that casual and multiplayer is very alive with stuff like Commander and other formats too
It has a splashy base effect, and you may find it better to wait until your opponent's end step, refilling your hand just in time for you to untap
