Rerolling is the action of uninstalling and reinstalling the game to reset your account. This is so that you can "roll" the packs to get the card that you want, and it's doable since the game gives the players free gems right after the tutorial. Some cards are generally considered better than others, which is why in a game of chance, people tend to keep retrying until they get the good cards without having to spend any money.
When rerolling the game, there might be times when you get something good but not quite sure if you want to keep rerolling or not. If this happens, you can save your account by making a Konami ID so you can return to it if you don't get anything better.
Lower rating means that you should reroll, higher means that you should keep the card. This rating takes into account the card’s rarity and availability within the game. This rating is subjective with the consideration of the current meta.
These cards are considered to be among the best to obtain since they are very useful and effective in almost any deck.
Most important cards for general use: 1+ Sphere Kuriboh (as many as possible; best card from these 2 sets), 2 Ladybug, 2 Wonder Balloons, 2 Shard of Greed, 2-3 Order to Charge, 2-3 Twister, 1 Trap Jammer, 1 Curse of Anubis, 1+ Michizure, 2 Yomi Ship, 3 Kazejin, 3 Suijin, 3 Sanga of the Thunder, 3 Bubonic Vermin, 3 Skelengel
Forgot 2 Stray Lambs for generic list. For non-generic cards:
For Water Deck: 2 Levia Dragon Daedalus, 3 Unshaven Angler, 3 High Tide Gyojin, 3 Big Wave Small Wave, 0-2 Piercing Moray/Needle Sunfish
For Ritual Decks: 1-2 Sonic Bird
For Clown Deck: 3 Dream Clown, 3 Crass Clown
Not reroll, but should be recommended or suggested. Like I said, this site is still recommending 3 battle ox. So it wouldn't hurt to dig for 3 of these currently. Lots of field skill decks use them for back up
Use 1 field spell card.
What is a field spell card?

no lol, when you use your gems on an account then you can't reinstall to have the gems again. Reinstalling the game will make a new account for you, but you have to bind it to konami account when you don't want to reroll anymore.
