As Pokemon Pocket continues to evolve, Blue may soar into prominence as one of the best cards in the game, but for now it remains an extremely safe option to add to your deck
The card still sees play and still can be very swingy, but graveyard hate in the 21st century has gotten prevalent and sophisticated enough that the card is nowhere near degenerate
Most people get confused and think this means you only mill 30 cards, because you copied Halimar Excavator 5x and there are only 6, but because all creatures enter the battlefield at the same time and "see" each other as Allies, the net effect is to mill 65x6 cards or 180
Some commanders directly incentivize this kind of deckbuilding more than others such as Animar, Soul of ElementsAnimar, Soul of Elements, Alesha, Who Smiles at DeathAlesha, Who Smiles at Death, and Uril, the MiststalkerUril, the Miststalker
