So you want an alternative option to buy three structure decks and mash them? Something not too hard to learn and no long combos to memorize? Well, I've got just what you need....
Paleo frog has been around in various forms for the past four or so years as a rogue strategy that always shows up in bigger tournaments. The deck revolves around traps and interrupting your opponent's lines of play. I feel this is the best way for a new player to learn the game as the more you play against different decks, the more you learn to counteract them. With combo decks you just focus on what you want to do.
This is a budget version of the deck so sadly you only get two copies of toadally awesome. Getting a third copy will be top priority as well as three copies of trap trick. Luckily, you can get those cards for perhaps 5 or 6 dollars more total. As it stands this will certainly hold you for a while at a locals level.
