Hmmmmmm. This is normally a black effect (Disentomb/Raise Dead). Green gets things like this with Nature's Spiral.

White... doesn't, mechanically, currently. Flavour-wise it definitely could though. White does have a long history of Resurrection/Breath of Life effects. In the past couple of years WotC have been restricting themselves to make white only resurrect cheap creatures (Return to the Ranks, Timely Hordemate, etc).

This... is a colour bleed. But it's a lot closer to acceptable than some of your other colour bleeds. I'm not sure what to recommend.

It's a pity the name doesn't fit so well with a sorcery saying "Return target creature with CMC 2 or less from your graveyard to the battlefield", as that'd be squarely within white's current colour pie.

I thought white did get this from time to time. It gets Remember the Fallen, after all.

Yeah, white is tertiary in this I think. Unlike blue or red, it gets to do this, but only on like one card per Standard cycle.

I think I'll keep it, it's only a slight color bleed.
