Insane synergy between Kalista and Tahm Kench!
Beginning of Game- Kalista ADC makes Tahm Support her oathsworm. Early Laning Phase: Kalista tries as hard as possible to get to level 6 ASAP. Upon hitting level 6: Tahm immediately exhausts someone to swallow them. Kalista ults Tahm to the friendly tower, and the turret wrecks them completely with the combined slows between the two.
This total BS strategy has no counterplay besides, well.. scripting... and who wants to do that? I really feel like it should be removed or something, but that's just my opinion.
