MTG Salvation

Basically, I feel as though a good way to fix the color fixing problem in MTG is to create more Basic lands so that people don't need to spend hundreds of dollars

The first of these is my dual concept

"Basic WU
Basic Land
This card enters the battlefield tapped.
When Basic WU enters the battlefield, sacrifice unless you pay {1}.
{t}: Add {w} or {u}"

So with this you see that I want the cost of making a card have no deck limit high

Now the Trip version

"Basic WUB
Basic Land
This card enters the battlefield tapped.
When Basic WUB enters the battlefield, sacrifice unless you pay {2} and return a land you control to its owner’s hand.
{t}: Add {w}, {u}, or {b}"
