Necrocharge (10) - This has Rush and Bane. (After this follower fights another follower, destroy that follower.)
Choose 1. (1) Select a Soulstrike in your cemetery and put it into your EX area. NC (20) - It costs 2 less to play this turn. (2) Bury the top 2 cards of your deck.
QIf my Necrocharge drops below 10 after this follower enters the field, does it lose Rush and Bane?
AYes. Its Necrocharge (10) ability is passive, so it is only effective while your Necrocharge is 10 or above.
