Combos Utilizing Urza-sq-s-Armor

force all opponents to discard all lands they have in play. fastbond and armor let you replay all lands

censor the word "ow" so evrytym u attack ur opponent, he/she gets 1 additional damage. u'll prevent ow's damage coz u have an armor

make the # of cards in your hand = the # of urza's armor you have in play. you don't take damage from attacks

you get a lot of mana without damage

get a bunch of small black creatures, kill them and get them back with unearth, and exhume, and do it all over again, until you have 20 counters on black market.thenpestilencefor20anddon'ttakedamage

Now using the Wumpus's ability dosen't hurt you.

urza's armor will prevent all damage and you wont take damage as long as urza's armor and delaying shield stays in game

play the armors and the humility, then pestilence for 1 and all their creatures die. you can use any card that deals 1 to all creatures

Note: this works for all pain lands. Add mana to your pool without taking damage. Can also absorb any damage from mana burning

just a win win situation
