Sigil of Brilliance

If target instant card has cost less than the total arcane damage you've dealt to opposing heroes this turn, negate it. (It does not resolve.) Meld (You may play 1 or both halves of this card. Each costs 1.) Deal 1 arcane damage to any target.

At the beginning of your action phase, destroy this. When this leaves the arena, deal 1 arcane damage to any target. If damage is dealt this way, amp 1. (The next time you would deal arcane damage this turn, instead deal that much plus 1.)

Once per Turn Instant -- Discard an instant: Draw a card. Essence of Lightning (You may have Lightning cards in your deck.)

Arcane Shelter 1 (If you would be dealt arcane damage, destroy this to prevent 1 of that damage.) When this leaves the arena, create an Embodiment of Lightning token.
