If I Hostile Takeover enemy unit, can I Hidden Blade it and draw 2 cards?

Yes, you can use Hidden Blade on a unit you have taken control of with Hostile Takeover to draw 2 cards.

Here is the breakdown of why this works:

1. Control: When you play Hostile Takeover, you gain control of the enemy unit. For the duration of the effect (until the end of the turn), you are considered the controller of that unit.
2. Targeting: Hidden Blade requires you to target a unit at a battlefield. Since the unit is now under your control and present at a battlefield, it is a legal target for your Hidden Blade.
3. Resolution: When Hidden Blade resolves, it kills the unit. Because you are the controller of the unit at the time of resolution, the effect "Its controller draws 2" will identify you as the controller and allow you to draw the 2 cards.

Important Note: Ensure that you have the necessary priority and that the unit remains on the battlefield when Hidden Blade resolves. If the unit were to be removed from the battlefield (e.g., by an opponent's effect) before Hidden Blade resolves, the target would become illegal, and you would not draw the cards.
