Since it's a Spellcaster-Type monster, you can also Special Summon it from your hand with the effect of "Magic Curtain"
This does change when you start looking at tournaments and organized competitive play, though
Cards like Crush Card Virus, Cyber-Stein, and Gold Sarcophagus were handed only to top finishers at Shonen Jump Championship events, so their populations are tiny, often around 40 to 100 copies
These cards are then resold on the secondary market or kept for a personal collection
How do you like it so far
To be honest, youre going to be playing against the starter deck a LOT before dealing with the bigger stuff, so you dont even have to have a completed amazing tier 1 deck to start
