Nice one and you had a 4 star UR Master Strategist. What Semaphore is saying is that just save it until it you will be having a prospective general to use the tickets for and most likely if it coincides with a platinum priest event. He stated on his previous posts that he is interested in getting an SSR Mori Terumoto and would use the tickets on an upcoming platinum priest event that includes that said general.
Semaphore and Foolinlove sure had a lot of tickets and SSR cards saved just for the platinum priest event, and luckily had several URs.
For inherited skill for Master Strategist, it really depends if you want for atk/def/speed/int bonus or damage multipliers/modifiers. My SSR Sanada Yukimura had a low damage before on the Takenaka Hanbei stage (Hatazirushi drop). But when I changed her equips, troop type to ghost ninja and her inherit skill to to the 2nd skill of SSR Honda (Tokugawa was included in the formation for the bonus to work), the damage ranges from 6k to 20k - depending on the triggered skills/abilities. So it really depends on what you really want it to be - for pve or PvP, or both if possible XD
