Green removal is usually fight effects. Ezuri's Predation is in my opinion a green board wipe. Maybe also Ratchet Bomb.

Got some problemos amigo:

Ezuri's Predation only can deal 4 damage to each creature on its own. (Second point.)

Ratchet Bomb only can hit permanents with the same cmc. (Third point under second section.)

Keep tossing them at me though!

Well, don't have many other real board wipe. :(
Heaven is kind of limited. It's basically Hurricane or Squall Line.

It has one... Wait, where is it?! I should definitely include The Great Aurora! How could I forget! Besides that, green is known for its ramp, so the more expensive colorless options are probably best for it.

If you play Heaven for then Earth for , you make your own Starstorm. Twice as expensive, yes, but it works.

Missing Duneblast, probably Death Cloud and maybe Killing Wave ?

All three seem great actually! Do you think Hex would count?

AEtherize, Engulf the Shore... ? What about number specific cards ? Dusk/Dawn,
Elspeth, Sun's Champion -3 ? Gideon, Champion of Justice ridiculous -15...
I'm not really sure so I'm suggesting different things... The list seems almost complete I think.

Hex is complicated because you need 6 targets otherwise it's a dead card. (Also bad against hexproof and shroud).
It can clear most of the board but not everything. I was also wondering about player specific wipe like Bonfire of the Damned.
Would that count or not because it doesn't kill ALL creatures ?

AEtherize is not on the list, because it only targets one player's creatures. Bonfire of the Damned fits here too.

Engulf the Shore is good sometimes, but the fact that you need other cards in play to hit the scariest creatures makes it seems too slow to be good.

Dusk, Elspeth, Sun's Champion, and other cards like that seem great as board wipes!

I don't put planeswalkers on my lists based on ultimates, because those are a goal all on their own, so Gideon, Champion of Justice won't cut it for this list.

Agreed, the whole point of board wipes is to destroy lots of things, even with hexproof. So Hex is not good enough.

As always, thanks for the help!

Duneblast

Duneblast is a great suggestion, thanks!

Black Sun's Zenith?

Also I'm confused about your "What this doesn't include" list. "Sorcery speed mass return to hand" is Coastal Breach and Devastation Tide, yes?

EgoGone, thank you, Black Sun's Zenith has been added.

Oops! Yes, you're right. I thought Coastal Breach was an instant, and I thought that since Devastation Tide can be cast as an instant since it has miracle that it could work, but it's nearly impossible to set it up like that.

I'm a pretty big fan of Ezuri's Predation as a board wipe.

Ezuri's Predation can only deal with 4 toughness creatures, which leaves the biggest creatures unanswered. To me, that's the whole point.

Edhrec shows that there are plenty of creatures that have toughness more than 5 that are commonly used, but rarely more than 6, so that's why dealing 6 is the cutoff point.

Armageddon?

Armageddon is unable to destroy all creatures, which the description describes as the purpose of the list.

Indomitable creativity?

jpsuchecki, I think that's a good type of card to add. I'll add other cards like it too. Thanks!

Desolation Giant is red isn't it?

Tosk, yes, it's wrong in Tappedout's database. That said, it's color identity is red and white, so you wouldn't be able to put it in a mono red deck anyways.

What about planeswalker abilities that fit these requirements?

Are you referring to Elspeth, Sun's Champion and Ugin, the Spirit Dragon?

Curse of the Swine perhaps?

This is a much-needed resource. I'm a huge fan of board wipes since a deck packed with wraths allows you to endure and win when the table decides that this is suddenly a game of archenemy.
