I guess if you just know youre going to want to tap your mana creature more than three times, Naga Vitalist has that going for it
When this creature dies, it deals X damage to each opponent and each planeswalker they control, where X is the number of land cards in your graveyard
Now, with the sale complete, the impact is no longer hypothetical
Basically, we're okay with a few cards that put +1/+1 counters on creatures but we tend to avoid more complicated versions (such as 0/0 creatures that come into play with +1/+1 counters) at common, although we're more willing to do something like that if there are a number of cards dedicated to a certain theme ( Darksteel 's modular, I'm looking at you)
Two enchantments I recommend are Rhythm of the Wild and Fires of Yavimaya
There are seven SIR Pokemon and four SIR Supporters and most of them are desirable enough to make this list
