Just a little idea that I am tinkering with, any help is very much welcomed.
Main combo-Lotus Cobrax3, Ruin Ghost and Tideforce Elemental. Play a land, get three mana, use one to tap Ruin Ghost, exile the land, return it, get three mana, use one on tideforce, use one on ruin ghost, exile the land, return it (you get the idea). From this, you can generate infinite mana, activate any landfall ability as many times as you want (a 999999999999/1000000000000 Steppe Lynx, for example), or activate a lands ability infinite times (infinite 0/1 saproling tokens, protection from every colour, so on, so forth).
KotR, Harrow and Lotus Cobra help with acceleration, Steppe Lynx and KotR are early-game attackers, Roil Elemental, Admonition Angel, Emeria Angel and Rampaging Baloths are late-game pwners.
Trust me, if you draw the right cards, you can just sit back and laugh.
