Withered Leaves G
Return target permanent card from your graveyard to your hand, if that card's mana value is lower than the greatest mana value among permanents that where put into your graveyard this turn.
Rain of Denial XUU
This spell cost 2 less to cast if an opponent has drawn two or more cards this turn.
Counter target spell unless its controller pays X. If that player does you may draw X cards and discard X cards.
While interesting at first glance. Both just seem too busy to be made.
Unrestricted returning a permanent to hand from the graveyard already only costs 2. So whatever restriction is pushing it down to 1 has to be fairly benign or it becomes too limiting.
The value of a soft counter that gives you benefit if it fails to counter is a neat concept but there's a reason this hasn't been done in 30 years and it's not because no one thought of it. It applies pressure in a way that that is only feels bad.
Return target permanent card from your graveyard to your hand if its mana value is lower than the greatest mana value among permanent cards put into your graveyard this turn.
silly brush up, but there you go
It has special applications I'm sure, but typically would be under-influential I think. An easy brush up on the functionality would include allowing return so long as any other permanent card was put into your graveyard this turn. Still not that much better than Noxious Revival, but it's trying harder. Full expansion on this would include, [so long as another permanent was put into a graveyard this turn]. This would cover creature loss, battle, board sweep; the whole 9 yards; yet still be somewhat restrictive on the application.
Rain of Denial will be hard to pull off more than once, I don't think it will be what you desire of it. Your opponent will be able to play around the restriction by postponing their additional draws.
