Of course, to really understand the value of Shorecrasher Elemental, we have to look at the other blue megamorphs in the set
The deck is uniquely built since it cannot play any card which costs less than 2-mana due to the Cascade mechanic, so it profits from the multiple free spells in the format
Of the two starters, its probably the winner but requires a bit more planning and thought for the best result
To convert this into a win, the deck employs finishers like Glaring Fleshraker or Walking Ballista, with Kozilek's Command offering a reliable way to tutor them up and end the game with infinite damage
Then we have equipment like Livewire Lash and Grafted Exoskeleton that have mad synergies with this self-targeting trigger
Given that Legends (the set that Hazezon Tamar was printed in) was released in 1994 (I was in high school!) I feel very lucky that RKF even still had a proof of the card, and it was a relatively reasonable price
