(To collect evidence 3, exile cards with total mana value 3 or greater from your graveyard.) You don't choose a target for Sample Collector's ability at the time it triggers
(This is useful, in part, because over the years Pokemon have gotten increasingly more powerful, with higher HP pools, damage output, and such.) Fairy Pokemon are fully in the past now, so you won't be able to use them if following rotation
Numeron Network One of the most important cards to the Numeron deck is the field spell Numeron Network
Flash creatures either function as one-for-one removal spells (Hired Blade), as two-for-one removal spells (Sentinels of Glen Elendra is better at surviving combat than Ashcoat Bear), and as flexible curve-fillers (Cloaked Siren lets you hold up interaction and have a threat if you dont need to use it)
Inside the game, you'll find cards from a variety of sagas
If a spell with rebound that you cast from your hand doesn't resolve for any reason, including being countered, the spell will be put into its owner's graveyard and you won't get to cast it again on your next turn
