When there are no counters left you can cast the spell without paying its mana cost
There are incredibly powerful cards in this deck, like Trazyn the Infinite which gains all activated abilities of artifacts in your graveyard when hes in play, and Biotransference, which turns all your creatures everywhere into artifacts, spreading the Necron influence across your deck
Necropotence Number 4 is the final card on my list with a named Magic period
Repulse (Invasion/Planeshift/Apocalypse) Cantrips are fun, since you do not have to spend a card to gain an effect - it breaks the card/mana equation of playing a spell
Its also a vampire demon, which is a very fun mix of creatures
ALL TAPPED OUT That was quite the torrent of TAUC tactics talk, so I hope we havent lost sight of why this is all so topical
