Just before Christmas, when I was looking for something different to play, I tried out this list in a tournament: U/G Megamorph. I went 2-2. Not very good, but the games I lost were still quite competitive and I think with some practice I may have done better with the deck.
But, here’s a great addition:
I would like to note that a [scryfall]Stone Haven Outfitter[/scryfall] / [scryfall]Ghostfire Blade[/scryfall] package could work here as well, but I’m not going to try to fit that in right now.
[deck]

4 Deathmist Raptor

2 Nissa, Vastwood Seer
3 Rattleclaw Mystic

1 Dispel
2 Immolating Glare
4 Silkwrap

2 Canopy Vista
4 Flooded Strand
4 Forest
3 Island
1 Plains
4 Lumbering Falls
2 Prairie Stream
4 Windswept Heath
[/lands]
[/deck]
The key to the deck is that you need to know when to just play stuff face up and when to use the extra mana. I won many games by playing a second round two-powered flier and just beating with it while using my other stuff to hinder my opponent.
