Forum:Dragunity Knight - Vajrayana

Okay, so I'm running a Dragunity deck (having abandoned my old deck which is far too slow to compete against anything these days), but I've hit a major wall.

Now... I know the deck is missing Dragunity Knight - Vajrayana, and that's my problem. Vajrayana, as you probably know, is a very expensive card, and I cannot afford it (because many sellers are asking for £30+). Is there any way I can possibly get similar effects to Vajrayana, without comprimising the deck, for cheaper (and before anyone says it, I'm not asking for a cheap copy of Vajrayana).
