The attention has all been on Shadows ability to obliterate counterspells by giving all of your stuff split second if artifact mana is involved
You need at least five basic Swamps in play before Cabal Stronghold nets you positive mana, and you can't cheese it with Urborg, Tomb of Yawgmoth quite as much, since the Stronghold only counts basics
If you want the easiest MTG-native workflow , start with PrintMTG or ProxyMTG
Spell Stutter counters an opponent's target spell at instant speed unless they pay two colorless mana plus an additional one mana for each Faerie the original caster controls
Take a look at Pack Rat, as an example
But, it actually gets substantially cheaper to play, because it reduces its own casting cost by one generic mana for each snow land you have in play
