Im building my deck irl and will eventually get blue robins, Sharena is just my budget card for now. Might go something similar to your Elise route until I can get my hands on more Sakuras since I have a playset of Elise. I actually had the same idea of running Lianna over Rowan, but I pulled him him from a box and wanted to give him a try. How has running Lianna worked for you?
Do you think I'll be fine subbing Sakura for Elise in the mean time for Black/White Corrin?
