Youre going to have access to potentially 9 cards with enough storm triggers on the stack plus 20 or more red mana
One small area of concern for this deck moving forward is that if mono-red aggro does see an uptick in popularity, the lack of maindeck copies of Cut Down may come back to bite you
The quote at the bottom of this card is very sweet, with it noting: " Cut and bruised from his climb to the summit, Zahr wept with relief when he saw the felidar's horns appear." This card also has a Lifelink effect, giving players the amount of damage dealt by the creature back in health
That said, Slurrk is my personal pick for the weakest legendary ooze
In a way, the core mechanics of what this deck wants to do aren't that dissimilar to Tinker Time - get lots of little units and resources out on the board fueling a larger plan, and gain additional benefits from those little assets to create an overarching (and overwhelming) plan of attack
Tapping is essential in Magic, and this merfolk protects that interaction beautifully
