MTG Salvation

Do you think it would help if I increased the other 3 in power a little?
Such as:
you gain 3 life
tap 2 target creatures
deal 1 damage to target creature, and 1 damage to that creature's controller

Quote from Alacar Leoricar

It's a nice idea, but the balance of the 5 colors is hard to disrupt. Perhaps if the saturated mana can be used as mana of its associated color. I think that's what you were going for, yes?

Yes it specifically says that

Quote from Monly

Nice idea, but some seem powerful (i.e. the -1/-1 and Green land)

Really? I thought the overpowered one would be the green. Keep in mind they are not basic, so limited to four a deck.

I had an idea for new types of mana that I call Saturated Mana. The 5 kinds of Saturated mana are Solar{A}, Ice{I}, Skull{K}, Fire{F}, Leaf{L}. Each of these has an effect when you add one ot your mana pool. They can be used to pay for cost of the corresponding mana, or pay costs for Saturated mana only, but can't be used as colorless mana.

Bright Prairie
Saturated Land- Plains (R)
symtap: add {A} to your mana pool
Whenever you add {A} to your mana pool, gain 1 life

Frozen Sea
Saturated Land- Island (R)
symtap: add {I} to your mana pool
Whenever you add {I} to your mana pool, tap target creature

Vile Bog
Saturated Land- Swamp (R)
symtap: add {K} to your mana pool
Whenever you add {K} to your mana pool, target creature gets -1/-1 until begging of end step.

Frozen Sea
Saturated Land- Mountain (R)
symtap: add {F} to your mana pool
Whenever you add {F} to your mana pool, deal 1 damage to target creature

Fertile Grove
Saturated Land- Forest (R)
symtap: add {L} to your mana pool
Whenever you add {L} to your mana pool, add G: to your mana pool

Then you could have spells that rely on Saturated mana

Vile Edict BB
Sorcey- (U)
Destroy target creature, it can't be regenerated

Spellthief 2{I}{I}
Creature- Human Wizard (C)
When ~ deals combat damage to a player, draw a card
1/2

Enraged Baloth 3GG
Creature- Beast (U)
Trample
~ gets +1/+0 for each {L} used to cast it
4/6

What do you think? Has this been done before? Is it even feasible?
