Enchant land

Whenever enchanted land is tapped for mana, its controller adds an additional two mana in any combination of colors.

Fear (This creature can’t be blocked except by artifact creatures and/or black creatures.)

Whenever a player casts a spell, sacrifice a creature.

Destroy target creature. It can’t be regenerated. You lose life equal to that creature’s toughness.

Enchant artifact

Enchanted artifact has “At the beginning of your upkeep, sacrifice this artifact unless you pay its mana cost.”

Door to Nothingness enters the battlefield tapped.

{W}{W}{U}{U}{B}{B}{R}{R}{G}{G}, {T}, Sacrifice Door to Nothingness: Target player loses the game.

{3}, {T}: Double the amount of each type of unspent mana you have.

Tap up to three target lands.

Flying

Whenever a player casts a spell, you lose 1 life.

Each creature has “When this creature dies, choose target opponent. That player puts this card from its owner’s graveyard onto the battlefield under their control at the beginning of the next end step.”

At the beginning of your upkeep, choose one —

• Put a +1/+1 counter on target artifact creature.

• Put a charge counter on target noncreature artifact.

Sunburst (This enters the battlefield with a charge counter on it for each color of mana spent to cast it.)

{2}, Sacrifice Engineered Explosives: Destroy each nonland permanent with mana value equal to the number of charge counters on Engineered Explosives.

{3}: Ensouled Scimitar becomes a 1/5 Spirit artifact creature with flying until end of turn. (Equipment that’s a creature can’t equip a creature.)

Equipped creature gets +1/+5.

Equip {2} ({2}: Attach to target creature you control. Equip only as a sorcery.)

Players skip their upkeep steps.

Sunburst (This enters the battlefield with a +1/+1 counter on it for each color of mana spent to cast it.)

When Eternal Witness enters the battlefield, you may return target card from your graveyard to your hand.

Whenever you cast an instant or sorcery spell, you may pay {1}. If you do, scry 2. (Look at the top two cards of your library, then put any number of them on the bottom of your library and the rest on top in any order.)

Whenever Fangren Pathcutter attacks, attacking creatures gain trample until end of turn.

Feedback Bolt deals damage to target player or planeswalker equal to the number of artifacts you control.
