Chamán fulgor solar

If the target leaves the battlefield or otherwise becomes an illegal target before the ability resolves, the ability doesn't resolve and Sunflare Shaman won't deal any damage to itself.

If Sunflare Shaman leaves the battlefield before its ability resolves, it will still deal damage to the target. If Sunflare Shaman is put into your graveyard, it even counts toward the amount of damage dealt.
