I wanted to build a Casual / Semi-Competitive Dinosaur deck without spending over $150 on hand traps and the little diamond alligator boy.
I wanted to make use of the overly powered cheap card, Double Evolution Pill, so I added a ton of non-dinosaur monsters and Extra deck monsters.
This deck benefits off of Extravagence but if you need to budget down more, that playset should be the first to go and replaced with an Upstart Goblin + 2 generic spells or traps.
