Alluring Inducement

Shiyana Specialization (You may only have this in your deck if your hero is Shiyana.)
When this attacks, the defending hero reveals their hand. You may choose an attack action card revealed this way. If you do, this becomes the chosen card.
Unity - When this defends together with a card from hand, create an Eloquence token under any number of heroes' control.

Shiyana, Diamond Gemini

You may have specialization cards of any hero in your deck.

At the beginning of your action phase, Shiyana becomes a copy of target hero until the start of your next turn, and gains "Cards you own are the class of your hero in addition to their other class types."
