"All increases you receive to your current HP from elemental sources heal you twice."
"Yes, it is affected by all sources of ELEMENTAL healing, including Antimatter. Non-elemental healing is healing from Other cards - namely, Shard of Gratitude and Shard of Divinity. This is to make their combinations with Shards not overly powerful."
Shards of Gratitude and Divinity do not get doubled.
Improved Miracle - the king of kings... can effectively heal to infinity-1. Provided you have buffed your max HP up... So 219hp healed max.
Improved Miracle heals to full health minus 1, regardless of this card. If you have 200 health, it heals you for 199.
And this card doesn't stack with itself.
Empathic Bonds stack. That's a potential 144 healing every turn.
Yeah, this is actually a valid point.
Again, this card was designed to make healing cards like Holy Flash more popular. Is it really that overpowered? It does not stack and it does not affect Shards. The only trouble I see is from Feral Bond...
