Urza, Lord High Artificer does something on his own though, he creates at minimum 2/5 worth of bodies on the board and can immediately tap the 1/1 he made for . Also if he and his token is allowed to live till presumably the next turn such as Turn 5 he can activate his own ability. Even if a land drop was missed with just four lands and his token. Which based on what you get after a quick shuffle can range anywhere from a land (awful) to a free cast of Omniscience (jackpot). This is because Urza still creates what is essentially a mana rock for his own ability if he is by himself.Quote from HugSeal »Quote from Forgotten One »The best comparison I can make with Urza, Lord High Artificer is with Prossh, Skyraider of Kher. Both are infinite with a particular card (Paradox Engine vs. Food Chain), and both cover two different bases with what the decks needs to function (Urza provides a mana engine along with the mini-Mind's Desire vs. Prossh providing Fodder and a sac outlet).
This analogy doesn't really hold up in my opinion.
Prosh and food chain is infinite all on its own and deterministically so.
Urza and paradox engine does nothing on their own and even when you get a bunch of mana rocks you are still not deterministically infinite since the ability can fizzle. Sure, with enough rocks and mana to start with you are very likely to be able to play your whole deck. But it is not a 2 card combo in the way foodchain prosh or flashhulk is.
Paradox Engine meanwhile does nothing by itself because its reliant on other cards in order to fulfill its own trigger-based condition. It doesn't create nonland spells in your hand to satisfy its own trigger to untap nonland permanents.
