Hashirama Senju [The Final Battle] does not have a skillbreak in EN. Right now, Pain - Tendo [Six Paths Rinnegan] skillbreak is the "dominant" position 1 for high spending meta. Hashirama is generally more available through recharge than Pain, but Pain is easily $1,000 USD+ in guaranteed four star (through Infinite Tsukuyomi and relying on other resources as you recharge that amount).

If you're a new player and not aiming for a high recharge life style, I recommend Obito Uchiha [Rage Mode] four star skillbreak. If you're willing to spend a little bit, Shisui Uchiha [Susano'o] and Indra Otsutsuki (both skillbroken) are solid. Obito will be a good crossover between affordable and viable (typically a lot of players can get him for 35,000 coupons during a Fukurokumaru Deals).

Regarding Fuku Deals...don't expect Hashirama or Pain in them.
