The fifth card is one of the Kuribohs from GX, and instead of being used to stop damage this one is a battler. You can summon it manually for two tributes, or special summon it at a chain link of three or more. Its stats are 500 x the number of spell cards your opponent has in their grave, but any spells used when he is on the field get banished instead of going to the graveyard. You can also only have one of them at a time. If you use a lot of spell cards this can combo well with cards like Gren Maju Da Eiza and Golden Homunculus. It can also help set up for Number 92: Heart-eartH Dragon, being a level 9 monster and banishing spells for Heart-eartH Dragons resurrection effect. This card seems to be pretty good on its own and with other cards.
