Arena Offense help

I need help deciding what red unit to add to my arena trio core. Right now I am torn between Corrin male with his new yato refine and defensive Tiki with warding breath and lightning breath. The one I go with will be +10ed
The team they would be on is with my +2 Kana(M) and my soon to be +10 Soren with special refined wind's brand and chill spd 3. Now should I use Supporter Corrin with his Special refine and double drive skills or stick with Tiki. If I go Corrin should I give lightning breath and warding breath to my Kana? Any feedback would be great.
