Menace
Whenever Izoni enters or attacks, you may collect evidence 4. If you do, create two 2/1 black and green Spider creature tokens with reach and menace.
Sacrifice four tokens: Surveil 2, then draw two cards. You gain 2 life.
If you can't exile enough cards to meet or exceed the required mana value, you can't choose to collect evidence at all.

Once you've announced that you're casting a spell, players can't take actions until you've finished doing so. Notably, opponents can't try to remove cards from your graveyard to stop you from collecting evidence.
