During a 2v2 battle,If one of the first two pokes has Unburden plus terrian seed,and another has the same surge ability,Unburden will not activate(HA slurpuff+psychicseed with TapuLele)
Plus,psychic surge is meant to protect onland pokes against prioritize moves,but ingane it turns out to disable onland pokemon to use prioritize moves against opponent,which gives airborne poke a big defence boost
Plusx2,HA indeedee and HA Cursola seemed has the same problem with previous rillaboom breeding bug.
Plusx3 some poke before gen 8 lost their basic tm move pool and some normal poke might wrongly evolve into galarian forms(zigzagoon)
