LA Hector + Dragons?

Setting up arena defense team, would like some advice
all units are 5 star no merge unless noted

LAHector- Standard kit + reposition, bonfire, Vantage, Ward Armor and Armored boots
A tiki (4* +10) Rally def/res Fury (soon to be warding breath) , Vantage, Drive def and Quick Riposte
Nowi- Mirror Strike, Rally Def, Vantage, Fortify res, and distant def.
Myrrh- Standard kit + swap, Quick riposte 2, and Guidance 1

Is this a good team for this week? Or does it need tweaks?
