Uncounterable (via boseju) Final Judgement, which is the card:Martyr's Cry (even though martyr's cry can't be made uncounterable by boseju) situation, only with better art and a more extreme mana cost.

Thanks for your feedback, YerpyMoose. Fortunately, Gaddock Teeg takes care of all the (that I know of) red chaos spells, bant tuck/wraths, and black wraths.

I never thought about the fact that card:Martyr's Cry can't be made uncounterable under normal circumstances. It can, however, be given a mana tax via something like Thalia, Guardian of Thraben and then made uncounterable, so it still needs to be considered unfortunately.

How will you deal with the new Gideon, Champion of Justice ?

Gaddock Teeg does more work than is fair...

I apparently cannot read (and if it got into play before gaddock?)... What would you say a "perfect" board position would be?

I haven't compiled a complete list of cards that cannot exist on the board before going off, because the concept cannot and does not need to account for that. If a pre-existing board state is detrimental to the end result, the deck simply does not get to be 100% infallible in this particular game, or alternately, striving to activate an Oblivion Stone , card:Nevinyrral's Disk or Magus of the Disk first.

I do know that the above-mentioned Gideon, Champion of Justice as well as Karn Liberated , Humility , some anthem effects, and some other cards will be a problem, but as I said I have not taken into account all cards pre-combo and Gaddock Teeg takes care of them all post-combo.

Seedborn Muse for Fog every turn? In multiplayer...

Triggered abilities are still untouched, save for the need to be non-targeting (of your things), bounce/exile/-X effects.

Uncounterable, over-loaded Cyclonic Rift , as well. Dovescape is a no go, it slips past Gaddock Teeg , and doesn't target.

Oh, and Trickbind works as well, so Boseju isn't the only card that can defy Dovescape, At least in facilitating combos.

Mr_Sam, that is actually a fantastic idea. Being able to Angus every turn is awesome. Might even do double duty, helping me untap monoliths and ETB tapped lands to ramp harder. Thanks!

YerpyMoose, Dovescape is more of a "for the flavor of the deck" inclusion and a card you can play in the spirit of the deck if you can't "combo out." Vexing Shusher would always trump Dovescape if I was truly relying on it. For the full invulnerability, Iona, Shield of Emeria + clone naming blue and white take care of 99% of problems. That is because 99.9% of problems for the deck belong to blue. Is it a bit degenerate to blue? Yes, but blue is a bit degenerate to most other colors.

The white covers, very importantly, Kaalia of the Vast which can sneak Dromar, the Banisher into play. I wish I had a more elegant solution, as the idea is not to stop all interactivity, or other harder locks could just be used.

you aren't allowed Dromar, the Banisher in a kaalia edh deck, wrong color combos! besides that, she is a nice lady who doesn't mean you or your friends any harm!

She doesn't have to be the commander. 5-color with Dromar and Kaalia would be the end of the fun.
