"for doing it fast you need better LR and GLR for getting those you need to buy them via summons with $"
 * You don't need to rely on premium summon LR cards to do extreme fast and stably. But to be able to do so, you should've been active on past events to continue to collect cards that can better your teams.
 * Multhitters for tower teams are advised if creating a fast tower team. Gilgamesh was brought back two months ago, and ABB last month featured a multihitter. But turn skippers are advised if going for a stable team. And we were given a lot of AW events that featured turn skippers. And a lot of tower side-FAW were turn skippers.
 * And as someone said below, GURs and LRs are largely sufficient. LRs are there to equip them with burst skill to hasten the fight during KO Chance. GLRs are just to make the fight even faster because of their 30M damage during KO Chance when they are in burst mode.

" or spend an eternity with the free tickets they give you on summons which usually don't give you jack squat"
 * The best cards for tower came from tower itself, i.e., the LR and the amalgamated GUR multihitters. If the issue is you can't reach a certain rank to get them, being active and continuing to collect the cards needed to better your tower teams which will in turn help you reach a certain rank. If you were active, surely, your tower teams should have changed for the better instead of remaining stagnant.
 * If the issue is you can't reach t500 to evolve the LR, mirror. And read below for my response regarding "your LR MM is impossible" part.

"Also getting stuff like LR Mirror Maidens is just mathematically impossible unless you spend at least 50$ on rods."
 * It's not impossible. I've gotten all my LR MM (I mirrored 7 LRs already) without spending a money. You just need to join all ABB rounds, be in an active alliance (for that 15 rings join bonus), and have an ABB team that can win most of the time.
