Thanks for you comment and suggestion TzickyT!
I probably won't add Regal Force. I've tried the deck with Shamanic Revelation for massive draws, but most of the times it ended up being situational, so I opted to change it by other cards.

Thought #1: Does Teferi's Protection work with Hazezon? Phase out the Sand Warriors, so you can have Hazezon leave the battlefield and come back without exiling.

Thought #2: Hazezon exiles ALL, not just yours, 'Sand Warriors' when he leaves. So there must be some cheap way to give your opponents that creature type, or all creature types, presto Hazezon becomes a one-sided Merciless Eviction.

Cybersix on thought 1, yes, I think that the first sand warriors would be protected by Hazezon's ability since they're all exiled at the same time, although I'm not sure. When they all return, Hazezon's ability will trigger again in the next upkeep and make more warriors, but if they kill Hazezon, then all the sand warriors will vanish. Anyway, Teferi's Protection is a great card and I think that I wouldn't mind putting one in here.
About the 2nd though, yes, there is a card that makes a one-sided boardwipe. It's Shields of Velis Vel. I tried it on the deck, but it usually becomes a brick on the hand since it only works with Hazezon on the battlefield, so I preffer using cards with more synergy with the rest of the deck.

For Clarity, cards that are flip cards, have a color identity of both sides. so unfortunately Westvale Abbey is both a colorless and black identity card. In it's place I suggest Sanctum of Eternity. It's a cheap way to get Hazezon back into your hand before the sand warriors enter the battlefield, without raising his mana cost by 2 more.

W15H I didn't know that and it seems that nobody from my playgroup noticed that either. Thanks for the heads up! I'll find a suitable replacement for it.

I think Rite of Harmony would be great in this deck. It would almost always yield at least 7 cards and the flashback cost makes it even better.

Brxndle yes, I have been considering Rite of Harmony but was not able to test it yet. Nevertheless, I belive that it will be a great fit in this deck.
