The final product line is being called Through the Ages and is 64 reprints of existing Magic cards with Final Fantasy flavor
Played on turn 1 and dealing with it immediately it already replaced itself, while dealing with it with paying for the trigger it already did its job in slowing you down and letting the player gain a tempo advantage
Aside from infinite combos with things like Chain of Smog, Toshiro Umezawa is probably of best use in the 99 as a Snapcaster Mage on steroids for key black cards
Until you realize they are fifteen cards ahead of you - including permanent resources on the battlefield - and just drew several extra cards, and if you don't kill them on your turn you're basically in for a redux, except they're going to have untapped a ton of additional mana
The Cascade trigger resolves, and the Fatal Push goes on the stack, on top of the Bituminous Blast
You can find my other precon upgrades here: Explorers of the Deep is a Blue / Green Merfolk deck with a +1/+1 Counter subtheme
