Ideally, Id update mine whenever a premier set like Ikoria: Lair of Behemoths releases so, about four times a year
This 2/3 for four gains you some life and card advantage when it comes into play
Its a card that demands removal and that can be handy for saving your other key players

This is an incredibly flavorful nod, but as far as the card itself goes, The Darkness Crystals mana value and activated ability are a bit too expensive to be exciting
When it comes to the gameplay, the Ruby cards have an aggressive style of play with glimmers that have good overall stats, on the higher end of Strength and Willpower, as well as traits or abilities that will force action onto the player or their opponent
