pokemon horsea card EX Holon Phantoms Common Card Type RARE! Horsea 49/62 1995 Pokemon

In formats like Modern and Legacy, this card is a staple in many sideboards

Using the Tenth Doctor card showing David Tennant in the role gives players access to the Allons-y! ability, that allows players to exile nonland cards from their deck and place time counters on them, and the Timey-Wimey ability, enabling players to time travel at the cost of removing time counters from their cards

If you dont know what your deck is trying to accomplish, you wont know what hands to keep, what to tutor for, or when to spend interaction

However, up until very recently, we've been pretty much in the dark about the set, save for a few pretty pieces of key art
