I'm def going to play around with it in a standstill variant, though I am entirely unsure if it makes more sense to add white or black to the deck. There were very few permanents over 3 in that list to start with, the biggest hit is losing crucible.
It also notably has interaction with LED as early as turn 1, which may in turn make it a very solid breach enabler.
Why Standstill? Of all decks, Landstill benefits the most from not casting spells - and when they do, they want to play counters. What permanents do Landstill even play besides Standstill and moxen? I mean in your above example, you get this card into play and then it doesn't do anything but attack for 3 because your very own Standstill prevents it's ability from being useful.
Well, if my opening turn is putting a 3/2 lifelink into play along with a standstill, a land, and maybe a mox, and maybe even a lotus, it puts faster pressure on my opponent than the deck normally could muster and all but ensures my opponent cannot sit around and wait. Think of it as a soft combo where you start with an 8 card starting hand and 1 is a combo piece every time.
In the best case scenario, this guy functions as a control finisher that does not cost you a card in your deck, gives you +1 hand size, always starts in your hand, cannot be thoughtseized away away, and cannot be drawn by accident when you are trying to draw into countermagic. That's a lot for a card to provide.
And the deck really need not play many more permanents than landstill and lotus because those are the ones you want to recycle most of the time, but breach is an option, most of the grave hate like Nihli spellbomb can be put back every turn once this guy sticks.
