That is wrong.

Assuming the result on a coinflip (and rounding prices to 1 for tickets and 2 for packs)

• phantom gauntlet gives more than you give: 1,15625 return with 1 spent

• keeper draft: 1,71875 plus the cards you draft with 2 and 5 packs spent

So unless you are looking for cards that are garbage in draft and that everyone will pass early (like items) keeper draft isn't worthy.

On the other hand, phantom mathematically "goes the distance". Bear in mind that even if overall you gain in "value", you will still need to pour in money, because you not always get the tickets back.

The greedy bast*ds should REALLY give back tickets even for 2 wins runs or at least (this one wouldn't accomplish much) give more tickets for 5 wins.
