I'd recommend U&Y over Bastet, assuming you have the Awoken forms of both. U&Y is 4xATK on a 4-color combo while Bastet is 3xATK on a 5-combo, and U&Y caps out at 20xATK (water-water-water-wood-light-dark combo) while Bastet caps out at only ATKx6 (7-combo plus use a skill) and only for wood-element cards.

Also, U&Y has a fallback, water-water combo for 3xATK if you can't do anything better, so you're not screwed if you can't pull out four combos.

EDIT: Oh. Checked your PadHerder and you don't have Awoken U&Y. You've got the Tengu and Wadatsumi you need but they're not evolved yet, so it'd be quite a bit of XP grinding to bring them up to speed -- you've got four days if that's the route you want to take.

Still, the U&Y you DO have is probably better than Bastet for the task anyway since their bonus is to God-type instead of Wood-attribute.
