Thanks for the reply.
Sure, the deck is not legal in pauper - it is a Peasant-deck.
If you're interested in Peasant-magic, check the "official" rules:
https://peasantmagicgroningen.blogspot.de/2009/02/peasant-magic-rules.htmlSince Peasant is no official format, there is no separate thread on deckstats.net.
I have listed my peasant-decks in the pauper-section, because pauper is the only official format which bears resemblance to peasant.
In order to distinguish between pauper and peasant, I have placed the (Peasant)-tag in front of the deckname
