So basically mini Drowning Mirror Force.
CHIM-JP078 心太砲式［トコロテンホウシキ］ J.E.L.L.Y. S.W.A.P. Cannon
Normal Trap Card
(1) When a monster declares an attack: Target 1 monster on the field; return it to the Deck
Note:
心太式 seems to be a term to smoothly produce Gelidium Jelly Strips, and an expression that basically means “Out with the old, in with the new”, or something to that effect.
砲式 is joke on a term for 方式 (Method/System) most likely, with the first Kanji replaced with the Kanji 砲, which means Gun or Cannon.
