Since we need to perm the glitched inventory by depositing one item from the character's inventory I grab the Key Tube and Red Card as a means of protecting the run. Bad RNG can cause you to either have to grind a while or just straight up miss these objects. The Key Tube is taken when we glitch Rolf's inventory at the start, specifically from accessing slot 0 which is above the "next" on the second page of items. The Red Card is from accessing slot 48 in Rudo's inventory which corresponds to Amy's luck stat. Note that you don't need these items specifically to perm the glitched inventory, and in fact it might be marginally faster to just perm it by depositing Laconiamets - although it would be a bit riskier. Hopefully that clears things up.
