IJN Izumo

As an additional cost to cast IJN Izumo, sacrifice two creatures

IJN Izumo gets +4/+0 and first strike whenever it attacks alone and gets +0/+4 and deathtouch whenever it blocks alone.

As long as IJN Izumo is the only creature you control, it gets +2/+2

“Sisters... eh. The Izumo class consists of just me, so I guess I'm a bit jealous.”
