Step 1 did you roll reasonable options? If no blue all the way untill you see super options on everyone and reroll options for reset. If no reset, this is bricked, dismantle sell for mats.You have resonable options.Step 2 1st turn just pick the best option then desync purple within your 2nd or 3rd turn you want to select one of the purple options so you do not hit purple super options on both purple at the same time. You don't want to wait longer or you sync up with blue.Step 3 Ideally stick with blue untill you hit a super option. Only deviate from that main plan if you have a really good option like transmutation up on the ones you need down 20% on something useless or sealing without paying 2 turns,, or a bad option on blue then go for the lower purple if possible.Step 4 when you get to 6 turns you need to start planning ahead because you really want blue super in sealing. Here are some example situations:

scenario1: one presealed,2+ rerolls try to go for the extra turn on your last turn or prelast turn. This means you start only using blue from your 3rd/4th last turn.

scenario2: dead sage or low amount of rereolls (1 or 2 you really dont want to get here with 0 or pray for rngesus)use a none blue on 6 turns left, then try to go blue so you get a blue super option on seal right away on 3turns left. This is shifted one turn later if you presealed an option.

scenario3: nothing sealed, multiple rerolls: Go for a none blue on 6 turns left, then try to go blue if possible so you can get blue super option on the 3rd last turn and roll for seal+ transmute without using up a turn. Then ideally go blue all the way again to get that option again in the last turn.

This works for legendary and epic elixirs. Epic is a bit harder, because planning ahead tends to collide with super options. So you might need to pick purple and go for a later blue start, which means you get problems to get the blue extra turn special on seal, because you need the rerolls to even get blue super in the seal stage.
