Alpha Investments

Cards printed in sets before 4th Edition (Alpha Limited to Fallen Empires) cost {3} less to cast and permanents printed at that time have Hexproof and Indestructible.
Planeswalkers lose all abilities.
{u/r}{u/r}{u/r}{u/r}, sacrifice a permanent with the modern frame (8th Edition to present): You may cast an instant or sorcery printed in Alpha to Fallen Empires without paying its mana cost.
