A vicious early game ICE, it is extremely flexible but needs tech like Vovô to keep paying for it economical. Sentry subroutine is extremely useful against every killer except Afterimage. Synergises well with Working Prototype and Thunderbolt, especially against Tsakhia "Bankhar" Gantulga, and against Slap Vandal by itself. NEXT Activation Command can make it a strong mid game ICE, and even a viable end game ICE against poorly set-up Arissanas. Mostly useful as a surprise (and nothing else) outside HB, but the current Shaper meta and the loss of Formicary mean that those Thunderbolt rez-derez decks, or any other HB deck using those effects, containing Stegodon and this ICE were basically killed in their cradle.

At the beginning of the card, this card is amazing! You can choose the correct type without a problem. Its self derez effect makes this ice expensive to use, unless you are also playing Vovô Ozetti. Paying 1 for a (possibly) 3 subs ice is fairly good. But 3 is too expensive.

This ice is obviouly meant to be played in Thunderbolt Armaments: Peace Through Power, where it would consistently get a 4th subroutine and +1 strength. Again, good if you have Vovô Ozetti.

Of note, those subs matters. And possibly getting 2 subs to fire makes this even better.

Considering all this, it is a fun idea for an ice, but will be a low priority ice (unless you are playing Thunderbolt Armaments: Peace Through Power). There are so many great ices in HB.

The art is trying to convey the effect of the card. The chosen animal (buffalo for barrier, snake for sentry and lion for code gate) actually help understanding the concept of the card. Which is also in the name of the card. Everything combo together really well. Well done!
