The Hive's main strength lies in its numbers, as opposed to the GSA the Hive has far more units. This is evidenced by the Husks being supplement cards, instead of being part of the assault deck. This was done so Hive players have more chance to draw a unit than anything else, allowing players to amass a swarm more quickly than the GSA. Although the Hive has a lot of "basic" units, without special abilities, the few who do have them are extremely useful in almost all situations. The Hive supplements, other than the Husks, offer the ability for a stack to go hidden, provide buffs and enable the Hive to steal an opponents unit or settlement for their own use.
The heavy hitters in the Hive's Assault deck are the Monarch and the Queen, partly because of their individual Attack Power,
and because of their special abilities. The Queen, for example, acts as a forward command post of sorts as she allows any
Kroglodite card drawn to be spawn on her location, instead of your Base card. This grants several strategic benefits as it
allows you to put pressure on your opponent. It is advised to keep your Queen safely out of immediate danger as she'll likely
become a target. One way to achieve this would be to use a Dig card and keep your Queen hidden.
Spawning Kroglodites on your Queen doesn't break her out of stealth, but drawing a card and immediately placing it on top of
your hidden cards will surely look fishy, and your opponent will know you are up to something.
The Monarch's special ability causes all your enemy's cards and stacks on a space surrounding the Monarch to attack with 25
AP less than they normally would. This is useful to counter any attacks directed at the Monarch himself, but its value goes
further than that. Alternatively, you can use this ability to provide any other stack or card next to the Monarch with some
protection. For example, you have two stacks next to eachother and the one without the Monarch is being attacked. You can
choose to reveal your Monarch to protect your stack or take the hit and keep your possession of the Monarch to yourself.
Individually both the Queen and Monarch are powerful and have various uses. When they are in the same stack however they have their AP increased by 25, granting them both a whopping 100 AP. The chance of this occuring depends on how careful you are with both cards as there is only one of each in your assault deck, the situation might cause a premature loss of one of these cards or you might be lucky enough to draw one after the other.
The Dig card is of great importance, as it allows a whole stack to dig underground and become hidden, leaving your
opponent blind towards your intentions. The usage of this card is highly situational however. You might be scheming
to send a small stack to quietly take out that pesky settlement your opponent has been getting a steady credit supply
from. You could be amassing a huge stack to destroy your opponents' base and wish to be as stealthy as under-the-radar
as possible. You could also be plotting to grab an Infection card and make your way to a Wild Card without giving your
intentions away. The possibilities are endless and largely up to your own strategic ability.
By far the most useful card the Hive has in its arsenal is the Infection card. It allows the player to take over virtually
any defeated card, be it an opponents' unit, settlement or even a hard hitting Wild Card. The relatively low chance of
drawing an Infection card, one in six, makes it a supplement card not to waste on a small stack that has little chance of
defeating an opponent, you'll want to use it to its fullest potential.
Wild Card creatures can be tough as nails, requiring a sizable force to defeat. In return, when bringing an Infection card, you'll gain a formidable ally and with it you will be a step ahead of your opponent. Essentially you're trading your Hive units for a Wild Card. What is the benefit of that? You now possess a single card worth equal to all your discarded units. Say you've been able to infect a Great Glaark Worm harnessing 300 AP of power and you attack an opponents' stack worth, say, 275 AP, you've won a casualty free battle.
Wether the initial cost is worth it, aswel as all other decisions you make, is solely up to you.
