The Chain Veil

The second loyalty ability you activate doesn’t have to be the same as the first ability. For example, you could activate a planeswalker’s first ability twice, or you could activate a planeswalker’s first ability, then activate its second ability.

After the last ability resolves, you’ll essentially be able to activate a loyalty ability of each planeswalker you control a total of twice during your turn. The timing rules for when you can activate loyalty abilities apply each time; it must be your main phase and the stack must be empty.

Each additional time The Chain Veil’s last ability resolves will allow you to activate a loyalty ability of each planeswalker you control an additional time. For example, if you activate The Chain Veil’s last ability, untap it, then activate it again, you can activate a loyalty ability of a planeswalker you control three times that turn.
