OF Beryl

Example of Tower 150-Clear by reddit user Belophen.

Through Opening Found V duped four times, she is able to do 4 extra attacks for every [Retain] card of hers owned in hand at the end of the turn. This can be very strong and relatively easy to pull off, for little effort, but has very clearly capped damage and few ways to improve it quickly or consistently. With seasonal cards like Contaminated Spores and Forgotten Grave, she can set up especially fast and shines for a lot of players, especially versus bosses with elasticity as she has one of the only multihit attacks immune to it.
