Buying a booster box significantly increases your chances of pulling a wider variety of cards, including those elusive high-rarity ones
5-cost Marco isnt the worst, hes a blocker that can be tough to remove from the field
Tamatoa, Happy as a Clam is also just a strong card in general for allowing you to get items directly from your discard back into your hand and play them for free when he quests
I wouldn't jam this into any generic Red deck as we have better sources of card advantage now (what a time to be alive!) and the damage dealt isn't going to be anything too crazy unless we have an opponent holding 15+ cards in hand
These designs are Universes Beyond at their best, and frankly, much better than many top-down designs from recent Standard sets
