What's with the worthy cause? You only have 3 creatures to sacrifice to it, and you really don't want to be sacrificing those creatures to it. If you have an angel in play, why care about gaining life?
Another thing, getting the angel into play is going to be tough unless you manage to mana drain a really nice target for it. There is the odd tinker as well, but still, unreliable method of getting the angel into play. Heck, even workshop decks have some trouble getting her into play, I fail to see how this would do it any better. And the fact that it is your only non-death/pseudo-win condition doesn't help.
Which is another problem. Decks are designed to win the game. This is designed to not-lose. That really isn't going to cut it I feel. You put no real pressure on the opponent other than eventually casting a 4/4 flyer. And if they manage to remove it, you have problems. And there are several ways to remove it in type 1. Removing it in response to the greaves equip. After its greaved, balance, and edict as well as disk and deed. And then theres always the get rid of the greaves then remove the angel plan. So, it seems frail to depend on only 3 artifact creatures as your only way to win/not die.
And the long cunning wish? Why bother. Either add more wishes or fix the board so it isn't tooled for wishes. Your whole board is nearly 1of instants based to abuse the wish, but you only run one, so it isn't going to be that effective. And speaking of the board, what is with the Haunting Echoes? Just as a board into a pseudo-win condition card? Echoes isn't all that great in type 1 because of all the 1ofs people run in decks, you aren't likely to get very much out of thier decks.
And finally, the mana base. OMG why?!? 7 Fetches, and only 6 lands to fetch? In a control style deck, that is just a bad idea. Only the one volcanic to support the 2 REBs in the board? Wasteland would completely destroy you. Heck, even 1 might be enough, but 2 would surely crush you, especially since you are planning on casting a 7 mana creature to win with.
And lastly, regrowth? WTF for? You have 2 ways of casting it, of which they can only be fetched with tinker. The mox emerald and the lotus. It isn't a reliable card, and it can't even be used for something else like forcing with when you can't cast it.
So in conclusion. Scrap the deck, it isn't worth it. It won't work. Just about any other decently constructed deck will crush you. You have no defense, and your entire mana base is fragile, especially when you depend on casting a 7cc creature to win.
P.S. Read the card before you build a deck around it.
and then go to at least 1 life and remove it, you would win
You dont need to remove the angel for you to win. It only prevents your opponents from winning. So the worthy cause is a completely useless card.
