At the beginning of your end step, target opponent gains control of up to one target creature you control. Put two +1/+1 counters on it and tap it. It's goaded for the rest of the game and it gains "This creature can't be sacrificed." (It attacks each combat if able and attacks a player other than you if able.)
Whenever a creature you own but don't control attacks, you draw a card.
Picked for what they do in Jon Irenicus's deck. When two cards do the same job, the one with the lower comes first. All of them fit Jon Irenicus's color identity.Mana ValueThe total amount of mana a card costs, all added up. A card costing two generic and one green has a mana value of three.

When Jon Irenicus's first ability resolves, the opponent will gain control of a creature and that creature will immediately gain “This creature can't be sacrificed” as part of the resolution of the ability. There is no window of opportunity for that player to sacrifice that creature before it gains the ability.
Color identityEvery color of mana symbol on a card, in its cost and in its rules text. Your commander's color identity sets the limit for your whole deck: every other card has to fit inside it. A deck led by a green and white commander cannot play a card with any blue in its color identity.Open the full glossaryUBPlayers write colors as letters: U for blue, B for black. Blue is U because B was already taken by black.PoliticsPolitics decks turn opponents against each other, making their creatures attack someone else or letting the whole table vote. Goad is the most common tool: a goaded creature must attack, and must attack someone other than you if it can.Open the Politics pageForced CombatForces creatures to attack, or decides who they attack, often with goad. In multiplayer it points other people's creatures at each other instead of at you. Bident of Thassa, Toski, Bearer of SecretsOpen the Forced Combat pageDrawDraws you extra cards. More cards means more choices every turn, and in a 100-card deck it is the main way to find the pieces you need. Rhystic Study, SkullclampOpen the Draw page+1/+1 CountersPuts +1/+1 counters on creatures, permanently raising their power and toughness. Unlike a temporary boost that wears off at end of turn, these markers stay put and stack up over a long game. Hardened Scales, The Great HengeOpen the +1/+1 Counters page+1/+1 Counters+1/+1 counter decks put small markers on their creatures that make each one permanently bigger, and keep adding more every turn. Each +1/+1 counter adds one to a creature's power (the damage it deals) and toughness (the damage it can take).Open the +1/+1 Counters pageCounter EngineAdds +1/+1 counters over and over rather than once. A counter here is a small permanent marker that raises a creature's power and toughness for good. It is not a counterspell, which is a different thing entirely. Something that adds them every turn makes your whole board bigger and keeps it that way. Hardened Scales, Corpsejack MenaceOpen the Counter Engine page
