It seems not. Here are some relevant things sharpo said or agreed with when discussing things with Punf:
- If you have a Trojan Duck, and I have Lawbringer Gryphon and no tech buildings, you can’t attack me.
- If you have a Trojan Duck, and I have Lawbringer Gryphon, no tech buildings, and two 1/1 tokens, you obliterate the 1/1s. Then you have no valid attack targets, so the attack stops, no base damage.
