Dark Primape and TR Mankey might not sound like much but they are

First off let me start by telling about the Jungle Mankey and Primeape. Mankey-30 HP, Pokemon power letting you look at one prize card each turn(either players), 1 Colorless-Scratch for 10, weakness of psychic, retreat 0. Primeape- 70 HP, 2 Fighting-Fury Swipes(20 times the number of heads from three coin flips), 2 Fighting-Tantrum 50(if heads Primeape is confused), weakness of psychich and a retreat cost of 1. What's this mean it means that Mankey combined with TR Rattata could help you get a certain prize card but that's about it. Primeape is okay but you would basically stick with Fury Swipes, using Tantrum as a last resort.

Now for TR Mankey and Dark Primeape. Just as a reminder here are the stats. TR Mankey-40 HP, I colorless-Mischief(shuffle opennents deck)1 fighting, 1 colorless-Anger 20+20 (if heads). No Retreat cost and weakness to psychic.Dark Primeape- 60 HP, PKMN Power- 30 damage when confused, 2 Fighting- Frenzied Attack, Primeape is now confused after doing damage. Basically you bring out a Mankey shuffle your oppenents deck, then start hiting them up for 20 or 40(PLus Powers, Potions, SPotions, ER,SER,and all trainers should would be a great help to him)then if they bring out a big pokemon evlolve into Dark Primeape and get them for 40 then a 70 or 50 to yourself. Either way its better then the original set.
