Third, while forcing blue would normally be a drawback, BUG pod seems to be the most value oriented already, so it's probably not that bad.
Fourth, you can turn GSZ into finding both early Vets and this creature.
Fifth, it dodges more counterspells, such as getting around Spell Pierce.
That said, it does have considerable drawbacks as well. It's a turn slower due to the mana cost, it's vulnerable to Karakas, it's a turn slower due to summoning sickness, it's vulnerable to many more removal spells than Pod is once it resolves, and you can't string multiples together. But, I would argue the GSZ tutor being a turn slower is not a drawback, because any tutor for Pod (which has more limited options) slow you by a turn as well.
I think the Karakas issue is the only issue that's really worth bringing up, unfortunately it is also a big one. It's not Legacy playable, though it might be modern playable.
