I'm currently building a Thrasios + Kraum deck which will mostly just be rammed with different combos. I've become known as a bit of a Dramatic Scepter/Paradox Engine abuser in my other decks (just finished a Lavinia + Knowledge Pool list too) and thought I'd stretch out what combos I can bring to the table. So far I have:
1) Rhythm of the Wild + Glen Elendra Archmage + Blasting Station. Quite hard to interact with providing the Rhythm lands first, also something outside of infinite mana/Labman wins (also in the deck) I'm known to go for.
2) Ghostly Flicker + Peregrine Drake + Archaeomancer. Aside from the drake, the other cards here have uses outside of the combo.
3) Ley Weaver + Freed from the Real. Infinite mana combo no.2.
4) Dualcaster Mage + Twinflame. Another combo where the individual pieces have some use outside of winning.
5) Deceiver Exarch + Splinter Twin. The classic infinite dudes finisher.
Other win-con cards outside of combos, but I want to use in the current list: Laboratory Maniac, Nexus of Fate, Jin-Gitaxias, Core Augur and Blue Sun's Zenith. What other combos (preferably non combat-damage/creature based ones) have others got in these colors?
