Creatures with recursive abilities that you can keep replaying, like Bloodsoaked Champion, are excellent options to include: If they die, you can just bring them right back and repeat on your next turn
While its price tag is still fairly modest, this card continues to rise, indicating that it may be even more expensive if the trajectory holds
Once per turn, during the End Phase: Send this card to the GY, and if you do, Special Summon 1 " The Winged Dragon of Ra - Sphere Mode" from your hand, Deck, or GY, ignoring its Summoning conditions.
[All Turns] When one of your purple Digimon with [Ravemon] in its name or [Bird] or [Avian] in one of its traits is deleted, by suspending this Tamer, Draw 1 (Draw 1 card from your deck)
Another observation is that the fake cards have more vibrant colour in their printing process, possibly because the technology today is simply too good and cannot replicate the old processes of an old card like Flooded Strand from Onslaught
This one is from the 1st edition base set, but a printing error meant that it has no rarity icon at all
