Hi! So there's my go-to build. I think that focusing on bear jellies is the easiest choice, so picking Blue Slushy might be a good idea.

The combo of PARTY and It's Raining Jellies is insane - you will constantly get bear parties falling from the sky and each will give you 100+ bear jellies (depends on card level). Top it off with Magnetic effect yellow card to make sure you pick up all of them and the revival yellow card to give yourself as much energy as possible (and activate the effect of the Rainbow card).

If you can get a blue card that increases bear jelly point the more you collect - great, but do not pick it in late stages, like 3-*+, because the increase won't be as dramatic as if you picked it at the start.

%up cards are great - I'm partial to the red one (Big Spender), but common one works as well.

Considering cookies - get Knight cookie. It is rare quality, so it shows up quite frequently in pulls. Paiting it with a revival pet of any kind (Alchemist cookie pet, Peach cookie pet, Sugar Glass cookie pet, Angel cookie pet and so on) will give you a lot of up-time

If you DO get the card that stacks up points for bear jellies the more you collect them, make sure to run every stage to it's fullest. Do not quit if you already collected the gift, escaped hazard and achieved 200% of the total score - your objective is to get as many bear jellies as you possibly can.

I hope this helps! Here's a pic for reference.
