This is a mid-range deck that caps out at six ink (not including the shiftable seven-cost Aladdin) and has a decent number of tools that will help you respond to your opponent's game plan while keeping the pressure on with high-impact characters
If you're using Urza, Lord High Artificer, infinite mana combos are more useful than infinite sacrifice combos
Also, that ward 2 isnt nothing
Of course, youd have to sacrifice one of them because of the legend rule unless you turn off the legend rule with Mirror Box, Mirror Gallery, or Cadric, Soul Kindler
Two types of cards are banned: generically powerful cards that would warp the format, like Oko, Thief of Crowns, and cards that prevent an opponent from leveraging their commander
Because R&D falls in love with it first
