Urza's Incubator

Put in my black/white cleric deck. Works great with Edgewalker. Most of the clerics in the deck cost 3(converted) mana or less to play so with those two cards out 90% of my creatures are free.

Put this in my combo tribal Myr deck. I put this in with Clak Klan Ironworks, sacrificed Myr Retriver to pull another one from the graveyard back into my hand and keep summoning them for free while sacrificing them to Ironworks and pumping up my mana until I get infinity and either feed the mana to Myr Matrix (to mass create Myr tokens by the millions), Goblin Cannon (shoot opponent over millions of times before sacrificing the cannon), or just go for Fireball.

This helps my Myr deck immensely (Yeah I like to play different fun decks). I use this with Krak-Clan Iron works and sacrifice one Myr Retriever, then sac another to get the first one back, and repeat the process and float like infinite mana, then either Fire ball my opponent and all his creatures, use with Goblin Cannon before it destroys itself, or use it with either Genesis Chamber and mass create an army of 1/1 Myrs that can all be tapped to make Lodestone Myr into a infinity/infinity trample creature, or and even use the mana with Myr Matrix to create even more while giving all Myrs +1/+1. Or for the heck of it have random Darksteel Colossuses in there and put them out there for kicks and giggles. with all the mana floating.

One of the best cards ever made put it into an artifact myr deck and mana producing myr like leaden, golden, magma, silver, and copper myr are free to play. Its an awesome card!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

this is a kick a$$ CARD IN A SLIVER DECK THE BEST WITH A SLIVER QUEEN

Thiscard is good for any theam deck like elfs,goblins,dragons.kavus,zombies,merfolk,but is perfict for a Chimera deck ia.Brass-talon,Iron-heart,Lead-belly,and Tin-wing Chimera.For instants if you get two out in play yuor Chimera are free to play,and free is a good price in my opinion

It's a nice thought, but this won't do you a bit of good with Sliver Queen. The Incubator specifies that your spells of the chosen type cost 2 less, but paying 2 to put a sliver token in play is not a spell, it is an activated ability, so the Incubator does not affect this at all.
