Silent Specter is on color, should you find enough mana to cast him normally, and is great at emptying the opponent's hand of options
But this can be reduced thanks to the card's convoke ability
Three Blind Mice Doubling Season Extravagant Replication What do I need to start this combo
So after looking at both Porygon-Z cards from this set, both are fairly even, they both have the same HP and retreat cost, and very similar moves, I like the first move on this Porygon-Z card better, but I like the main attacking move on yesterday's card better than today's, so you really can't go wrong with trying to incorporate either card into a deck
Hope this helps you out with brewing and tuning your decks
I need to experiment more with this card, but only when Im in Sage
