pokemon card game base set Complete Master Set (102/102) 1999 [MP-DMG] muscular depiction of Poliwrath captures the raw From Base Set to Present:

And four mana to pump one creature +2/+2 also seems underwhelming

7-cost EustassCaptainKid, 3-cost Roronoa Zoro, 4-cost Trafalgar Law, and 1-cost Nami are the strongest cards in this starter deck, but they can be picked up in other boxes, so you arent forced to buy the ST10 to collect them

In multiplayer, if you gain life, you want either to gain life in giant chunks (a la Invincible Hymn) or when doing other things (a la Kitchen Finks)

Ral starts as a card advantage engine and becomes a game ender if you can get the emblem in play

Notice that if your warped-in creature gets removed from the battlefield before your end step, then it will end up in whichever game zone a normal creature would , rather than in exile
