Trigger Duals

[Upinthe]

Of all of the cards I've introduced here, I don't think I've ever done a single land card. Mostly because I think they are kind of boring. Anyway, heres my first attempt at ia set of duals:

Forsaken Island
Land

At the beginning of your precombat main phase, add B or U to your mana pool.

Drawbacks:

1. Mana burn
2. Cant use them for instants most of the time
3. Doesn't work with Mana Flare, Wild Growth, etc..

Current Wording

I'm just going to start with the green ones for now. Does anyone have any ideas for names?

Name: ??
Land

At the beginning of your first main phase, add G or U to your mana pool.

Name: ??

At the beginning of your first main phase, add G or W to your mana pool

Name: ??

At the beginning of your first main phase, add G or B to your mana pool

Name: ??

At the beginning of your first main phase, add G or R to your mana pool

I always like enemy colors for lands but I also think it should be precombat.  Then you can use the mana for activated creature abilities such as basking rootwala.  I think these are a really big drawback and would rather take 1 point of damage off a painland than have one of these.

It should be "first main phase" since stuff like relentless assault/savage beating gives you two precombat main phases.

The cards have been changed. I need some help with names though.

These work well with Winter Orb and Tangle Wire. I think the drawback is steep enough but I would like them to tap like regular lands and turn off too!!
