Monster Sanctuary Release date: 2020 | Steam Creature collecting meets metroidvania in Monster Sanctuary
Because we'll create many Clue tokens, Five Hundred Year Diary can create a good amount of mana for us, and you can even sacrifice it to draw a card, as it is a Clue
Creatures that enter with -1/-1 counters on them become effectively immortal when you have Mikaeus on the field, so all you need then is a sacrifice outlet like Phyrexian Altar and you form a loop that lets you draw infinite cards and create infinite mana (until you deck yourself)
Its part of what has made other collectibles, such as Labubus which come in sealed blind boxes, popular as well
Graphically, the game is solid
These errors are well-documented, so check online first to see if your card is potentially part of this printing mistake
