You could save words this by saying "choose a basic land type" and targeting the players. It's an interesting mana fixing effect, although I'm not sure how relevant that is on a 5 drop.

> At the beginning of your upkeep, choose a basic land type and any number of target players. Each land those players control is the chosen land type in addition to its other land types until your next turn.

Thanks for that. I made those changes. I think, in a green deck, you could expect this to come out sooner than turn 5. Especially in a commander game.

Sure. I just meant that if you have 5 mana, regardless of the turn, you will likely have access to most or all of your colors. This could also be your landwalk commander XD

Well, it combos well with a lot of stuff from unlimited era, when "I hose your entire mana base" was a thing. Tsunami etc. But yeah, if you mana ramp into this, you almost certainly have all the colours you care about - so using it as mana fixing is mostly pointless. Nice when you can, though.

I know all that. I was thinking more about politics and team play when I made this card. I want it to be more useful in a EDH, THG or Archenemy game. I suppose I could make it smaller. I just don't like indestructible gods coming out too early in the game. Also I think it can be very easy to get manascrewed in one color when playing lots of colors. Also don't forget about boosting things that count the number of lands you control like Kalonian Twingrove
