Wondrous Crucible Wondrous Crucibles first ability is like buying the baseline tier of a home security system, for when you want to keep people from touching your stuff but you also want to save some money and not spring for the Avacyn, Angel of Hope Tier, or even the Privileged Position Package
For 2 mana, you get other effects that are better like Animate Dead
It is improved with cards like Skullclamp than can give some expectation of getting back to seven cards in hand
And if you drop Liliana, make a zombie, and pass, theyve got to deal with your planeswalker because its ultimate is really scary
in play, but itll also grab every land your opponents control as well
Haste enablers are especially prominent in Goblin decks, which can easily become overwhelming with Krenko, Mob Boss or Krenko, Tin Street Kingpin at the helm
