3x venom snake
2x venom cobra

1x lightning voltrex

traps
2x ambush fang
2x damage=reptile
2x rise of the snake deity

so i ussualy start with swamp and terraforming so i am ok on that domain,but i dont have monsters(summonable that is). i would like to be able to put up a fight from the beggining. i would also like to be able to deffend my monsters , and it ends up to both me and my foes having empty field. so any suggestions?
