In theory, you could play Invasion of Xerex to bounce something, use Yorion to blink the battlefield, and then use the battle to bounce Yorion, Sky Nomad, which would essentially let you blink your entire board each turn if you had enough mana
Depending on your goal, the choice is all yours on which Starter Deck to get (or both), precisely the reason I like these Starter Decks for the upcoming Ursula's Return expansion
Wormhole Serpent CMC: 4U Type: Creature Serpent Rarity: Uncommon Stats: 3/5 First ability: 3U: Target Creature cant be blocked this turn
Any permanents will do, including lands, tokens, or even the planeswalker being attacked
It also involves a bit less math, as it just gets three +1/+1 counters per creature you exile, unless you have counter modifiers in play
