Can you use a Unicorn to remove an Alien that has been placed onto a Protector in your field?
Yes, and that is a pretty good use of the Unicorn's powers.
Can you use a Unicorn to remove a Manticore from my field?
Yes, and that is an excellent use of the Unicorn's powers. When the Manticore is removed from your field, you will increase your hand size by one card. You can use a Unicorn to remove a Carbuncle from your field as well. Why would you want to do that? Well, that's for you to figure out.
Can a Siren lure farmers that are stacked beneath protectors?
Yes. Farmers that are called away by a Siren should be relocated to the assigned herd, leaving the Protectors in place. The only exception is the Anubis; their amazing powers protects your entire field from all attacks, including the call of the Siren. This means that a field protected by the Anubis is immune to the call of the Siren.
What happens if there are no cards in the discard pile?
You cannot 'Take the Discard' because there is nothing there to take. Any cards that have abilities that allow you to take cards from the discard pile will also not be able to use those abilities if played while the discard pile is empty.
Let's say I used a Chimera to create a super herd of Chickens and Cows - do I need all 8 chickens and all 8 cows to Herdvana that herd?
Yes - you need ALL animals of each type in a super herd in order to achieve Herdvana for that herd. If there are four animal types in the herd, all four need all of the animals in order the achieve Herdvana. This can be a positive or a negative depending on how you strategize.
Can I use multiple Chimeras to combine multiple herds to create a extra-mega herd?
Yes! This is one of the most fun things about the Chimera. You could end up with a herd containing multiple (more than 2) animal types throughout the course of the game. This increases the chaos, makes the herd easier to steal, but also easier to defend, and ultimately much harder to achieve Herdvana. Again, this can be a positive or a negative depending on your strategy.
What happens if a chameleon is used to defend against an attempted steal with a card that has abilities?
If the defense is successful, the person who played the chameleon would get to use the ability of the card used in the attempted steal.
What if multiple cards with abilities are played in a turn, causing you to end up with more cards in hand then you would usually have?
This is acceptable, you just won't draw cards at the end of your turn, until you are back down to the normal amount of cards in hand. As an example, if you defended an attempted steal of a Phoenix herd with your own Phoenix card, the Phoenix's ability would be used twice (once for each Phoenix played, assuming two Phoenix's were played). This would result in you drawing 2 cards from the discard pile into your hand to end your turn. Then, you would not draw a card on your NEXT turn in order to get back down to the normal amount of cards in hand.
If a Basilisk is used to discard a Hydra from an opponent's hand, who gets to use the Hydra's ability?
No one. If the Hydra is force-discarded from someone's hand via another card's ability, the Hydra is "dead" for the the rest of the game.
I was turned to stone by a Gorgon - can I still defend myself against steals during the duration of my being frozen?
Nope. Taking "no action at all" means you cannot defend yourself either.
I am confused about the Anubis card. How should I place it in my field?
Since the Anubis protects your entire field, you should place it above all of your cards. See the illustration below for clarity.
