Yeah obtaining duplicates for any card in Pokmon TCG Pocket is nearly completely down to how lady luck favours you
Especially as they have shown that they are willing to put non Lore or original printings into these sets
Considering that there are ways to Reveillark this (since its a 2/2) and other shenanigans, you can set up all sorts of infinite combos and reanimation loops with the Guide, generating extra mana, death triggers, and more
A turn one Moana, Self-Taught Sailor, can be followed by Skull Rock, Isolated Fortress, on turn two
Wisdom of Sea and Sky booster packs are the only booster packs to offer Baby Pokmon right now
It is possible to blink this or loop it through the graveyard to empty opponents hands fairly easily (and can be tutored with the Starfield Shepherd)
