You could do some old school speed with a bunch of choose the blocker...
Armorbearer, Maharia, Claudia, ET, lots of draw threes, Obedience of Noah, Provisions, Lamenting Jephthah Daughter.
You could try a green/(insert any decent color) preblock ignore with Hidden Treasures.
Defenses tend to be a bit easier cause you basically just pick a color. The problem with cheapo beginner decks is that to be competitive they need an offense that can actually win battles. That's hard to do with very limited access to the newer cards.
Afterthought: A heavy recursion oriented white offense might work well too. Lost Coin Found, Moses and Elders, Elders of Jerusalem, Blessings, ACiB, Scarlet Line, Ignores, a convert or two.
