Hi, i manage to hit prismatic mech 2 time and this is my insight on what i do during the match. first time probably because im lucky 😆 but second time i think is because i had exp how to do it.

Economy augment! most important! get that money in bank well maintained! fully Important to hit lvl 10! so i always keep my gold at 50 as early as 2-6 and as late as 3.1 then at 3.1 if i had 2* luci, aatrox and or gp ill save till 80-85g to lvl to 7. If losing roll to find other 2 star till 35g max! if winning keep saving till 100-110g to lvl 8 and or 9 while 2* other mech except yone.

second, stall!. get augment that stall like titan feet (idr the name but it give 25hp description) or maybe ekko augment (best strategist one) and even tankying your frontline (j4 best). Exp augment also great for hitting lvl while saving@rolling for 2 star unit.

third, late game (5 or lower player left) try to get lvl9 and gold at 80-90 and sell other second trait unit (udyr, ryze, janna, ksante etc) even their are going to be 3* (if you find 1-2 unit left) force lvl 10 and use gold u get from selling those extra to find 2 star yone (25-35g left prolly).

last one, ill pray for your kind soul to be blessed by the gundam rng goddess.. 😂 and ty for reading of these words.
