During your opponent's turn, at damage calculation: You can discard this card; you take no battle damage from that battle (this is a Quick Effect).

By using Astral Barrier along with Kuriboh, you can protect your monster and Life Points at the same time.
Kuriboh is a Fiend-Type monster which is bound to be sent to your Graveyard. You can use it to hasten the special summon requirement of Dark Necrofear.
The Unhappy Girl synergize well with Kuriboh since it can't be destroyed by battle when it's in attack position and Kuriboh can negate the damage that you will receive.
Tribute your face-up Kuriboh in the field to special summon Kuriboh Tokens as many as possible. Those tokens can be used for stalling and tributes except for tribute summon. You can then use Detonate, destroy those tokens then destroy cards that your opponent controls depending on the number of Kuriboh and Kuriboh tokens destroyed by Detonate.
