This is ridiculous, please ban this card! This is nonsense, the P9 have no place in Arena at all! What are you guys and girls thinking in Seattle???

Oracle of the Alpha needs a nerf.
While I love the idea of playing with the power nine, this card is just overpowered. Compare it with other mythic rare, alchemy, 3-drops, and it's clear that this card is vastly more powerful than it has any right to be.
Oracle can scy for you on each of your turns, and it is in blue so drawing or tutoring in to one of the best ramp or extra turn spells in mtg history is pretty easy. My suggestion would be to give all copies of the power 9 "as an additional cost to cast this spell discard a card" when they are shuffled in, and/or to make oracle be a 2/2 that doesn't scry.
[Ethereal Escort] is a 3/3 lifelink that gives a creature in your hand lifelink, no card advantage, barely helps in a lifegain matters deck.
[Spara's Bodyguard] has a more prohibitive mana cost and gives you a 3/3 with a shield counter, or a delayed 4/4. A 2/3 flyer that scrys for 3 with one blue or a 3/3 with shield for exactly 3 colors, this does not make sense.
[Ghalma the Shaper] is a 3/3 with vigilance that gives tokens and a card in hand to buff artifact creatures when he attacks. Against most decks Ghalma will need protection to attack and survive more than once. Oracle has flying, and only needs to enter the battlefield to get most of its value.
[Jarsyl, Dark Age Scion] requires heavy deckbuilding restrictions and can whiff ending up as a 3/3 for a more restrictive mana cost than OotA. Even if Jarsyl hits, it only takes 1 lightning bolt before combat and you have to wait another turn. Again, OotA gets most of its value upon entering, so unless it's countered, or the opponent happens to have Elesh Norn MoM, there is nothing stopping ancestral recall in to time walk.

Why the heck was this card invented for Arena??? I almost finished the guy and now he’s entered into an infinite loop of shuffling cards and creating more mana, completely for free. I don’t even know how many rounds he played alone, this sucks

I made it to turn 5, before my opponent literally had 4 turns in a row, and he beat me with the "deal 50 life card if you have 50 life", while still having another 5 turns he would play before I got another one. Ban oracle of the alpha, and/or remove time warp from it's card list.

Oracle of Alpha has turned alchemy into an unplayable format. Decks can be constructed that easily take infinite turns. I can’t believe it happened in the first place, let alone this long. Bye bye alchemy. I’ll never trust wizards enough to craft a card in this format again. You already lost no matter what you do.

In what Universe could any Card Designer think this is good for the game?
Cards have been banned for much less. Just saying...

Oracle of the Alpha creating the Power 9? Fair enough.
Oracle of the Alpha not exiling itself leaving the battlefield or being copied? And we thought Scapeshift was ban worthy!

That was a 60 card deck to start with! I'll let you do the math how many Timewalks were actually cast!

This card is absolute cancer to the game.
I played some jackhole abusing the **** out of this card doing absolutely nothing except basically MTG masturbation, playing his cards over and over take infinite turns while doing nothing to actually advance the game and win. I left the room for like 20minutes and came back and the player was still going.
