maybe tokinko's spells should be more akin to the actual drop rule? this would also help make needles much more useful since currently they are "use once" units.
i.e.
resummon last: consume blood to resummon the last friendly unit that died. if the spell is used multiple times, it just goes further back in the queue of "killed friendlies". units revert back to their pre-upgrade status when resummoned, and you cannot summon on the far 3 rows (or the shogi upgrade tiles, or the enemy home tiles. all the same thing) to prevent easy checkmates or instant promotion. might also make relic choice more interesting as you could also resummon killed relic units.
not sure what the second spell would be, but I wouldn't mind tweaking the silver star summon so that it can only summon near tokinko (and maybe at a cheaper blood cost too). this would add a bit more power/fortification to tokinko's own position since she has no escape mobility.
i know regn generally does not want to tweak tokinko/ancient king because of staying true to the original games, but would making tokinko more akin to shogi be worth pursuing?
