It's impossible to review this card without comparing it to its little brother, Wall of Static. For 1 more, you get 1 extra strength, which at first glance seems like a fair, or even somewhat good, trade-off. However, under a more thorough analysis, I don't think it holds up.
Here's why. Both cards are, for all intents and purposes, trying to fulfill the same role. A cheap, quick defense against face-checking early remotes, or alternatively, an early hurdle for centrals that most runners can't leap over in the first few turns. However, at fulfilling that role, it does a worse job than the all too familiar Wall of Static, for one reason—economy.
Early on, money is tight for the corp, barring a first turn Hedge Fund. And even if you do get an early operation for money, unless you're playing NEXT Design: Guarding the Net, you'd usually rather spend your first few installing ice, or an early drip like PAD Campaign. The earlier you get your drips going, the more they can pay off over the course of the game. Additionally, leaving your centrals undefended for long is often disastrous.
And in these first few turns, which is the only time either of these walls has a chance to be relevant, 1 is a big deal. A very big deal. And 1 extra strength, in those first few turns, usually isn't. If you're forced to rez this on the runner's first turn, it's probably worse for you than it is for them. Your credit pool has likely shrunk so much that most other ice you have out can't be rezzed. You also have to keep an extra 1 on hand at the end of every turn just to have the option of rezzing Bastion.
This, of course, isn't even considering the fact that there are usually better options than Wall of Static too. Weyland has the excellent Ice Wall, Jinteki has Himitsu-Bako, HB has NEXT Bronze, and NBN has Wraparound, and Resistor is coming very soon. Bastion's higher strength usually won't matter much later on either, as it only costs a credit more to be broken by either Corroder or Cerberus "Lady" H1.
In summary, if you want early-game ice, use in-faction stuff first, then WoS or spend a few influence to splash another faction's if you need a few more. This does little more mid-game than other, similar ice, and if it has a place in a deck, I haven't found it yet.
