Rulings

From the The Hunted release notes

You can discard a hybrid card (i.e.. Assassin / Ninja in the type box) to pay the cost to activate this ability.
When Arakni, Black Widow’s activated ability resolves, the targeted Assassin attack gets +3. If the attack had stealth at the time of the resolution, the attack gets the on-hit triggered-static ability.
The card is banished face-up into the owner’s banished zone.
The opponent is the hero banishing a card, which does not satisfy contracts that ask you to banish cards.
Arakni’s second ability triggers at the beginning of your end phase. When this triggered effect resolves, you revert to your base hero. There is no priority for any players during the end phase of a turn.
