Deep Lurker > Serpentine Spy
Deep is it's name, and Destroying is it's game.
Apparently, it also Lurks as well, because it has the Opportunity ability that enables the monster to:
"Attack from any position and will target the enemy Monster with the lowest health."
Sounds pretty similar to the Serpentine Spy that I wrote about in my last post, right?
Yup.
But the Deep Lurker has a very strong advantage to that of the Serpentine Spy, and that is HEALTH.
Boasting 6 health instead of 1, and couple that with Kelya Frendul's ability to apply +1 Shield, it makes Deep Lurker hard to kill.
If you have the Mana and Water and Fire monsters are options, then it may be a better idea to choose the Deep Lurker over the Serpentine Spy.
Of course, the Deep Lurker will set you back 6 Mana, but...
But, seriously, as always, don't put all your eggs in one basket. If you're going to choose the Deep Lurker, ensure you have enough Mana to choose other monsters that will help you succeed.
Again... trust me.
