Khalim's Open #5 (Blue Jump)

I believe this is one of the best decks in the current meta, very fast and reliable, has a great mid-game and late-game strength.
1 important note tho, Blue mainly was very popular cause of the transformation effect that denies alot of value from ur opponent, since humbling vision is cheaper and kinda more effective than frogify, people tend to not run frogifys at all, in my opinion frogify is still needed, its the best removal for blue, specially if u have that many creatures to support it. you can cut it and play more creatures, i personally tested it, i ended up losing to some specific effects that i couldn't deny with transformation.
