It's widely known that [EDH] is very broken. Building a superdeck is quite easy. So what defines you as a player is [...] how you show restraint and creativity while still remaining a competitive player and a good sport.
the only problem with urza is that he is an oldwalker, so its abilities would be like:
+3: remove up to ten target permanents from the play
-2: win the game
-8: kick your opponents in the face, then win the game
starting loyalty: 100
what about diabolic tutor?
you can't forget about him, even though he's completely worthless and any more than 1 in a deck is actually decreasing the value of the deck unless it's combo, in which case it sucks still as long as its standard legal.
Insidious is such a hoot in multiplayer games as you can get your combo on top of your library just before your turn or before draw. Just stack ancestral, timewalk and few other spells on top and you are rolling :).
