There are more efficient ways to play two cards in order to draw two cards in Warrior.
It's a combo that breaks even and digs you 3 cards deeper into your deck for 6 mana.
6 mana, play 2 cards (Scalper, Boots), draw 1 card (boots), deal 5 damage w/ rushing Scalper(and presumably remove a card from your opponent), draw 2 cards.
But I'm not sure if that's good, in particular because Rocket Boots is just bad on its own, and Scalper is suspect on its own. And that's a lot of mana for something, as you said, Warrior doesn't actually have much difficulty doing.
Yeah these weird combos tend to never work out. When a card is only in a deck for one other card it never ends well. There would have to be other cards that Ticket Scalper and Rocket Boots both synergize with in the deck in question for that combo to ever see play.
