"Vadis" is a trap that special summons 2 "Exosister" monsters from Deck with return-to-deck restrictions, incentivizing the player to time the trap's activation correctly and immediately use the summoned monsters' effects to perform 1-card-Xyz summons
Whenever a Hamster, Mouse, Rat, or Squirrel you control enters, you may attach Sword of the Squeak to that creature
When you add something, are you supposed to remove something
If the situation for Ritual Summoning is not feasible, you can use the effect of returning to the hand in addition to the summoning effect, so the damage is small
I would expect them to be the same since I never heard of there being a difference before, let alone 2 versions
Neither have great card quality either so you tend to have just work with what you have got
