More players = you win.

Kill the other base before they kill you. If you are attacking each other, it just comes down how strong your quest deck is vs. how strong their raid deck is. If your quest can kill their raid faster than they can do to you, you win.

The other actions add complications. Barrage and summoning will do damage to a base, which changes how much of their raid deck you have to beat before you win. If their base is barraged all the way down to 1% HP, for example, you will only have to beat their last team of 3 (strongest 3), or sometimes even only 1 or 2 of their last 3.

Summoning Orland or Bahamut gives your union an ATK buff, which means when you attack a base your deck gets a free ATK boost. This will let you kill them faster.

Summoning Lorelei or Bahamut will heal any of your bases that are not being attacked by them. So if you see an arrow pointing from an enemy base to a friendly base, that base will not get healed.

So basically, make sure you understand how the rules work and build a strategy around exploiting the tools given to you.
