Cacoliope and Euphié

Magecraft — Whenever you cast or copy an instant or sorcery spell, each player discards a card, then draws a card.

Delirium — Whenever an opponent discards a card, that player loses 1 life and you gain 1 life. Then if there are four or more card types among cards in your graveyard, create an Elixir token. (It's an artifact with "{1}, {t}, Sacrifice this artifact: Put a +1/+1 counter on target creature, then regenerate it.")
