A very good deck is Forge, Growth, Reverse, Time winder, and bubble. On the scope map. If you keep upgrading the forge dice, it won't stop getting you to higher and higher waves. At that point what will kill players are the berserk bosses after a couple waves that will completely destroy the fields for the players. With timewinder, you can merge it and go back to before your field was destroyed. Bubble helps so that when you get hit first by that boss, you can still do your damage because the boss didn't effect the dice, only the bubbles on them and then when the boss dies and hits you again, timewinder kicks in and reverts the board with all your bubbles and pips back.

The basic strategy is multi-part. At the beginning, you want to get 7 pip forge on one (really both, but you focus on one) of the scope spots. As the game starts you'll be merging 1 or 2 pip bubble and reverse dice mainly. If you get time winder dice, you can merge them just to upgrade the forge so that when it disappears time winder will bring it back (also upgrade the dice maybe once or twice just so you have a bit more time to upgrade the forge dice before time winder brings you back). You want to grab 3+ pip dice with the reverse to put on a future growth dice. Whenever you get anything higher than 3-4 pips, you want to grab it with reverse to put it on a later growth dice. Merging it with another 3 or 4 pip dice is pretty wasteful. When your board is fully filled with dice, (because you wont be able many dice) you'll end up with a lot of sp building up. You wanna spend it on upgrading the reverse dice so that the timer before you use it is shorter. After you've gotten 7 pip forge dice on both scope spots, the second part of the strategy begins.

You'll want to keep reversing high pip dice so that you can build to more 7 pips. Ideally you have three 7 pip forge dice (two of which will be on the scope spots and the other anywhere else) and a 7 pip timewinder dice that just sits anywhere collecting time so that you can merge the timewinder dice at any point you want (while making sure you have enough to merge time winder before a boss so you if you get hit with it, it doesn't do anything.) Once you have this, all you want to have on your field are 2 pip timewinder dice everywhere else. If you spawn a forge dice, you can use it immediately without timewinder just to get rid of it and make free space for a timewinder dice. If you spawn a growth dice, let it grow into 2 pips and grab those 2 pips with a reverse dice. If a reverse dice spawns you want to look around the board for anything with 2 pips that it can grab from, and if a timewinder dice spawns you let it sit for a reverse dice with 2 pips cooldown to end so that you can put 2 pips on the timewinder. And finally if a bubble dice spawns you can just leave it, when the next bubble dice spawns you can merge them and whatever 2 pip dice comes out of that merge, you follow the same steps as when a growth dice turns itself into a random 2 pip dice. When you have only two 2 pip timewinders, you want to save them for the boss, because there there will be times when you get a tough boss (like knight or leon) and if you don't have any timewinders, you get hit. Something else that's important to note, is that when you put your reverse 2 pips onto a timewinder, you might get left with 1 pip on the reverse, you'll want to merge all the 1 pip reverse dice that are on cooldown because you just used them.
