On a totally separate note, you have the makings of a hard-to-kill High Elves restricted team for Siege.
Lyssandra, Arbiter, Incarnate & Islin. Islin needs to be built in Regen with as much HP, Resistance & Defense as you can stack. His passive makes him crazy hard to kill.
I run Arbiter, Fyna, Incarnate & Islin and it typically takes a Galathir to beat me. It is my second most succesful Defense Team, and goes many Sieges w/o being beaten, or even attacked.
