Tip for Pear (Public version)
For each level, you can explore 3 times, and then keep worshiping to level up
If you are in your max level, keep looking for card that fit the level you are in
for level 1 - the transform card is ideal to put more damage and block with low mana cost, try to find more card that can draw more. cub assult, fluffyball, chill out, and drift away is recommended.
for level 2 - bonk is ideal to attack and weaken the enemy's attack, find some wash cycle and bottle of milk, you can draw the card with bascially no cost with this combination. Oh, a box of chocolate work too. In fact, I am wonder if reshape can turn empty box back to full chocolate again. be careful for enemy that deal several attack at one time.
for level 3, roil, milk flow, overflow is recommended. This is where you can put Pearls actual potential into use. Keep drawing the card, and make sure to empty your deck at the end. swirl is recommended. Look out for enemy that give you debuff if you attack them (this is why overflow with milk is a great duo in this level, plus overflow can deal damage to all enemies at once).
