>>44874977Here's a comparison of Cynthia without 1 EQ tile (left) and turning it into 2 Atk (right) ones. Either works really fine. The main difference is in the mega form (bottom), the data is from top-center to bottom-sides: no sandstorm/boosts, sandstorm + boosts, sandstorm + boosts + crit (no CS2 involved [yet]).
The tldr would be: 1 EQ tile deals ~20 more damage than +10 Atk while only using EQ. Meanwhile, the latter would deal ~35 more in the other moves.
