Mozex

I wouldn't use four Maze's End. Cut it down to two or three copies. After you draw the first one the rest are typically going to be wasted.

You Delvers only have about a 1/3 chance of flipping. You might be better off replacing them, or a different creature, with Pillar of Flame.

I see lots of black in the sideboard but barely anything in the main deck. You could replace dreg mangler with deadbridge Goliath and disentomb with revive to cut out black. A more focused mana base usually helps things perform more consistently.

Looks like fun. My only thought for change would be oblivion ring instead of pacifism, but that does depend on your meta game.

I would remove 2x grounded from the sideboard and replace it with plummet and/or snare the skies.

17 lands seems a little short. I have a little experience with urban burgeoning and it would allow you to run fewer lands in a flash heavy deck, but only two seems like too few. I think the deck would be stronger if you took out the 2x forced adaptation and added the last two urban burgeonings.

I like this deck's name a lot. It looks pretty solid too.

20 lands doesn't seem like nearly enough.
Where are the goblins for voracious dragon to eat?
I think Dragon Whelp is better than Furnace Whelp so you might want to switch the ratios.

I've been trying to find ways to break immortal servitude also. Thanks for sharing :)

If you want to win through infect then don't include kiln fiend or invisible stalker without a means to give them infect. This deck would perform more consistently if you focused on the Kiln Fiend strategy or the Infect strategy.

If you want to go infect Invigorate is an amazing pump card.

I would consider using rancor over spectral flight.
