Quite an interesting creature in aggressive decks as it can be a free 2/2 creature. Sometimes you can chain one into another into another. It’s more probable in Limited due to the 40 card deck size versus 60 in constructed.
I’m not convinced this thing will be good enough in Constructed but people will try, that’s for sure! I like it personally because in older formats you can play it on turn to into something like Umezawa’s Jitte which is great.
If you bring a bunch back from your graveyard via something like Living Death you get a mana refund which is kinda cool.
