I've never seen Teammates in a Vespiquen deck but it does make sense here - rather than Revitalizer, which limits you to grabbing Grass-types, you can grab something like an Eevee and an Energy to pull off a surprise Espeon, or perhaps a surprise type-change Eeveelution, a DCE out of nowhere for a Divide GX, a Band or Compressor to boost damage, or all kinds of other interesting combos
No matter if you focus on a single format or try to keep up with everything, knowing the scale of the card pool helps you make smarter decisions
For 1 mana and the cost of exiling a card from my own graveyard I can make a 1/1 Spirit
