Gotcha. That is not my typical Live Arena Team. I use Razelvarg in one of my Classic Arena preset teams, but that may be the first time I have ever used him in Live. In Live, I am typically full on Defense/Resistance Tank with Siphi, Harima, Pythion...
However, I fought Comacaz two fights in a row and he wiped the walls with me the frist time, so I knew I needed a different plan for round two. Rabbit was actually there to setup Wukong & Ramantu (got banned) with the Increase Accuracy buff to ensure the opening Ramantu A3 and/or WuKong A2 would land w/o trouble.
now that makes a lot of sense :)
