Wagic, the Homebrew !?

Very good:

I created the Groundswell letter, but when put into play does not work well, always gives +4 / +4, the code I used is as follows:

[card]
name=Groundswell
target=creature
auto=2/2
auto=@movedTo(land|mybattlefield) 2/2
text=Target creature gets +2/+2 until end of turn. -- Landfall - If you had a land enter the battlefield under your control this turn, that creature gets +4/+4 until end of turn instead.
mana={G}
type=Instant
[/card]
If you can tell that fails, it would greatly appreciate, I have watched many agreed and I have not gotten it to work.

Thank you very much
A Salute

P. S. I do not speak English, it is translated with Google, sorry if something bad writing

this card will actually be added soon...

replace auto=@movedTo(land|mybattlefield) 2/2
with this...
auto=aslongas(land[fresh]|mybattlefield) 2/2

Thank you very much for the help, I work properly.

I put the full code in case anyone wants to use.

[card]
name=Groundswell
target=creature
auto=2/2
auto=aslongas(land[fresh]|mybattlefield) 2/2
text=Target creature gets +2/+2 until end of turn. -- Landfall - If you had a land enter the battlefield under your control this turn, that creature gets +4/+4 until end of turn instead.
mana={G}
type=Instant
[/card]

Thank you very much

With the fresh thing you can code this one too:
This is the first one that came to my mind, don't know if there are more!

Regards!
