(Artifacts, legendaries, and Sagas are historic.) Essentially, The Fourth Doctor lets you play with the top card of your library revealed only to you

It also helps that, at full discount, Treasure Cruise is only (U) instead of (U)(U) that's required to cast Dig Through Time

You can then turn these cards up for their mana value

The +3/+3/+3 while stacked lets you quest aggressively while dodging most non-evasive challenges

While Narset, Parter of Veils unsymmetrical effect is obviously superior, playing either of these cards in conjunction with other tax cards from this list such as Archon of Emeria and Winter Orb you can quickly make sure that you wont be invited to play any Eternal formats ever again
