Orzhov GuildgateHow it plays out.
Basically, you accelerate and drop big guys, eventually draw or search for Warstorm Surge and wreck everything.
Alternative cards to put in.
Replace 1x
Meteorite with 1x
Darksteel IngotPros
The deck is faster than it looks and very consistent, you're guaranteed to be ahead in mana due to the acceleration cards.
You won't run into mana issues due to the mana fixing from the guildgates and the traveler's amulets, once you draw into a darksteel ingot or meteorite, you're gold.
The majority of the creatures have flying, making it difficult for your opponent to block.
The majority of creatures pack a punch so once you get them rolling, doesn't take long to kill your opponent.
The card draw is solid overall, you almost never get into a topdecking situation.
Immune to mill (sorta) due to Kosilek.
Lots of combos.
Cons
Can run into some issue vs specific combos since it has no hard removal or counterspells.
The original version without Anger of the Gods can potentially run into trouble vs really fast aggressive decks.
Has no healing but technically, the resolute archangels should do the job.
Enjoy! Feel free to criticize it as well. It was a personal challenge to create a deck with a balanced range of colors.
Edit: Revised the deck to face off weenies.
