Magic: the Gathering in the UK
I was thinking today about the synergies between various Rise cards and Warp World. The Green and Red Creatures that make Spawn tokens would be perfect for either providing the mana to cast Warp World or extra permanents when you actually cast the spell, which would then make more Spawn Producers. Mnemonic wall would let you return Warp World to your hand ready to be recast in the same turn. You could then finish your opponent off with something degenerate like using 20 mana from Spawn to activate Spawnsire of Ulamog into the three legendary Eldrazi. Or just Warping out Iona and Emrakul.
Is this even possible? It's definately something I'm going to try out at some point. Any suggestions would be welcome.
