Traitor

State
When you play a Trusted Companion, +1 Buy and discard a card.
A basic village for players that need the +Actions. You can get a one time huge burst of money for those willing to betray man's best friend for life. There's no going back, once a Traitor always a Traitor. Should be noted the money you get for taking Traitor will also not be do able again, which should qualify for once per game, so once done, any future turns plays of Trusted Companion becomes a +1 Card, then Discard a card, +2 Actions, and +1 Buy.
The money burst was originally a flat +$4 for 1st Trusted Companion and no additional $ for the rest of the copies of Trusted Companion played that turn. I decided to go with this scaling version to reward players who got lots of copies so it is more exciting and when done it hurts more to have many copies of the bad card in your deck.
Example mega turn play 1st copy of Trusted Companion, +1 Card & +2 Actions. Then play your 2nd copy of Trusted Companion choose to take the Traitor so you get +1 Card & +2 Actions & +$3. Then play your 3rd copy of Trusted Companion so you get +1 Card & +2 Actions & +$3 & +1 Buy & Discard a card. Then play your 4th copy of Trusted Companion so you get +1 Card & +2 Actions & +$3 & +1 Buy & Discard a card.
End result gain +4 Cards, +8 Actions, +2 Buys, +$9 and discarded 2 cards. (cost 4 cards, 4 actions)
Net result -2 Cards, +4 Actions, +2 Buys, +$9.
