Upheaval

W, Sacrifice this enchantment: Exile target creature that's attacking you or a planeswalker you control.

Dakkon enters with a number of loyalty counters on him equal to the number of lands you control. +1: Surveil 2. −3: Exile target creature. −6: You may put an artifact card from your hand or graveyard onto the battlefield.

Kicker 1 (You may pay an additional 1 as you cast this spell.) When this creature enters, if it was kicked, target land becomes an Island for as long as this creature remains on the battlefield. This creature gets +1/+1 as long as an opponent controls an Island.

Whenever you cast an enchantment spell, you gain 1 life and draw a card.

Split second (As long as this spell is on the stack, players can't cast spells or activate abilities that aren't mana abilities.) Target player sacrifices a creature of their choice.

Converge — When this creature enters, each opponent loses X life and you gain X life, where X is the number of colors of mana spent to cast this spell.

Target player shuffles their graveyard into their library. Prevent all combat damage that would be dealt this turn.

Flying Whenever Yusri attacks, choose a number between 1 and 5. Flip that many coins. For each flip you win, draw a card. For each flip you lose, Yusri deals 2 damage to you. If you won five flips this way, you may cast spells from your hand this turn without paying their mana costs.
