Arthur has two Hypers, one of which will generate copies of the other.
This card has varying effects depending on which player triggers it.
- When this card is triggered by an opponent, the player who set the trap will steal stars from the affected unit equal to 1x the norma level of the player. In addition, the affected unit will draw a card from the center deck.
- When this card is triggered by the player who set it, it will have no effect.
Arthur's Hyper is his main, if not only, form of strategic play. Branch Expansion Strategy turns his entire hand into Rbit Hobby Shop, which can then be placed around the board. However, unlike a normal trap, this one does not disappear after being triggered, instead remaining on the board unless it is replaced or destroyed.
Much like when playing, it is advised that the player wait to use the Hyper until they have a full hand, to maximize the amount of Shops. However, when he has a full hand, he should use it instantly so that he can start using his passive as soon as possible. When playing as Arthur, the amount of stars gained are directly correlated to the number of Shops on the field up to his current level, so Arthur should focus on setting as many Shops as possible no matter what. One should generally place a Shop regardless of one's current panel, except for panels. Arthur is also not incentivized to use multiple hypers since having 3 shops is almost always enough to snowball to a massive advantage and it can replace cards that Arthur wants. However its still generally worth to use at least a second hyper if Arthur's hand is full of cards that he doesn't want.
Effectively, the trap forces players who trigger it to pay Arthur to draw a card. While the amount of stars stolen per trigger may seem rather minuscule at first, it only increases as the game goes on and Arthur gains more Levels and places more and more Shops, as the function of the Hobby Shops work in direct conjuncture with Arthur's passive. In late game, it can be dangerously effective at preventing other players from achieving Normas.
One thing to note though is that although Arthur does steal stars from people whenever they land on one of his Shops, he generally wants to avoid people landing on them. The reason for this is because his passive already gives him a massive advantage in star gain. Also his shops can be overwritten by traps, so whenever someone lands on a Shop, they can either place a trap, or gain a trap that they can place on it. This will cause Arthur to lose stars in the long run, so its best advised to try and get Shops in locations that are hard to step on, although his nature of placing shops as fast as possible makes this hard to do. One thing, however, is that he really should avoid placing Shops onpanels. This is because people are far more likely to land on them, and thus be able to overwrite them with a trap.
