Against control decks, you can keep ticking up both copies, forcing your opponent to either keep discarding cards or simply risk dying before they can get rid of both
Currently the decks are selling for between $60 and $70 on Amazon (check with your local game store, they might have an even better deal) and at this price all of the decks seem like fine buys, assuming you want the new Doctor Who cards

A Fire type Pokmon, Reshiram only has 130 HP, which is pretty low by contemporary standards, given that the game is currently dominated by ex and V Pokmon with 200 HP and up, reaching way over 300 HP in many cases
