This is the NEWEST variation of bait with the new and improved fire spirits and one of my favourite cards in the game, the princess. Bait decks have always been a strong archetype, they require you to control the tempo of the match and often play defence through offence. This deck is slightly unusual because it doesn't have a big spell so you will rely on the chip of the goblin barrel. The inferno tower and princes are both strong defensive units that can be used to take down heavier units. The inferno tower works well at kiting tanks, hog rider, ram rider, balloon etc and you can use the princess opposite lane to help chip away. The main role of bait is fairly self explanatory, you will be looking to bait out spells like log, arrows, snowball or zap and then punishing your opponent with the other units. All the cards inside this deck can be used to bait out a spell in one way or another which is what makes this deck so strong.
Princess can offer a lot of defensive value because of her long range and splash ability. Try to protect her from the opponents troops and keep her alive as long as possible, this can help bait out a spell. Against a graveyard deck you can play her behind your king tower to keep her out of spell range of the poison or tornado.
This card is your main win condition and works great on offence for applying pressure and forcing your opponent to play defence rather than offence. One thing i noticed from kidkid (today's pro player) is that he will use this card on defence if his goblin gang is out of cycle.
Fire spirits can be used to help manufacture and elixir advantage on defence, they can deal a lot of damage to support cards and can also be used to support a prince or princess on offence. These guys can also be used to counter a goblin barrel or skeleton barrel if the correct timing and placement.
Early game you can start out with an offensive goblin barrel, ice spirit, fire spirits or placing your princess in the back. Try to learn what small spells or splash units the opponent has inside their deck and if you can bait them out you can then use the goblin barrel to punish them. Try to make positive elixir trades on defence and then punish your opponent on offence.
In double elixir you can start ramping up the offensive pressure while trying to stack up multiple princess' which can offer a lot of value. You can try tricky barrels if your opponent has barb barrel or log and is managing to keep up with your cycle. Please let me know what you think of the newly buffed fire spirits in my youtube comments!
