If it will be released, it'll probably be a "once per turn" card. A swift calculation, if you were able to use it 3 times in 1 turn: Using this card on Shark Drake Vice to summon Constellar Pleiades (5 Xyz Materials) Use Pleiades to summon Constellar Ptolemys and use him to summon Gaia Dragon (7 Materials) Use this card on Gaia Dragon to summon a random rank 8 monster and use it again to summon a rank 9 for a monster with 9 Xyz Materials.
So I'm very certain that it will be a "once per turn" card.
Only: what's the chance you draw 3 of these AND still have the cards left to get an Xyz monster on the field? Any deck has better 4-card combos (or even more cards required, but taking the minimum which is: 1 Xyz monster already on the field) if they were allowed to choose any 3 cards from their deck to their hand and place another on the field.
Mystic Shine Ball x3 to Dark Mist, Rank-Up to any Rank 3, Rank-Up to Utopia or Shark Drake, Chaos Xyz Utopia Ray or Shark Drake Vice, Rank-Up to Constellar Pleiades, Chaos Xyz Constellar Ptolemys Messier 7, Chaos Xyz Gaia Dragon, the Thunder Charger.
9 Xyz Materials. Lol.
On a serious note, I don't think this card would be printed as is. It gives anyone access to Xyz's that are exclusive to Archetype/Attribute/Type; Dolkha and Laggia would be everywhere with any Rank 3 engine, for instance.
But then again, Konami needs to print another broken card some time or another...
