Eviolite Makes Dhelmise Tanky. But you never want to Lead with it, so there's just one Copy. BE Eevee counters Umbreon by Evolving into Leafeon turn 1. Leafeon is your Ramp and Early Attacker, it'll help you set up Dhelmise. With Eviolite and 1-2 Venusaurs healing it for 30-60 Damage, Dhelmise becomes really hard to get rid of. Not to mention the most important tech in this deck: You can Blue Provoke your opponent's Megas/EXs and LOCK them into the Active Just concede if you lead Dhelmise
